BEHIND THE SCENES (ANTI-MATTER MAN)
Lost in Space "The Anti-Matter Man" (Season #3 December 27, 1967)
The episode begins with Will and Dr. Smith. Will is reading a book aloud to Dr. Smith. The book is about alternate dimensions, universes, and realities. The book also mentions a dark parallel world in which everyone has an opposite duplicate of himself
or herself. The next scene shows this opposite world, in which we see an opposite of John Robinson and Don West plotting to
escape the opposite world and come to the real world.
Next is shown John Robinson and the Robot. They have taken out the atomic motors from the Jupiter-2 and are working on them
outside. The motors are huge and John is standing in between them. John orders the Robot to turn the nuclear motors on. As
the Robot does this, the duplicate John Robinson suddenly appears. The duplicate is wearing chains, one around his neck and
others about his arms. He is dressed in a black and white uniform.
A lightning storm begins when the duplicate appears. The Robot becomes alarmed and shuts down the atomic motors. When he does
this, both John Robinson and his anti-matter self disappear.
Don and Will rush to the Robot to find out whats going on. The Robot tells them that when he turned on the nuclear motors,
John disappeared. Frantic, Will wants to go after his father immediately. However, Don thinks it would be safer to wait until
the electric storm passes through.
Maureen, Penny and Judy are all upset that John is missing. Don convinces them all to go to bed, and that they would find
John the next morning when the electrical storm had passed. Will, however, cannot sleep. He goes back outside to where the
nuclear motors are sitting. The Robot is also outside by the nuclear motors. Will and the Robot decide that they will recreate
the accident in which John disappear. Will and the Robot turn on the nuclear motors and get between them. After a few seconds
they both disappear.
Meanwhile, the evil anti-matter John Robinson and John Robinson are in the anti-matter universe. Huge white boulders are
everywhere. The evil anti-matter John begins to drag matter john with a chain down a pathway of small white trees with no leaves.
Evil anti-matter John pulls the chain and good matter John falls upon his face on the pathway. When good matter John looks up,
there is also an evil anti-matter duplicate of Don. Evil anti-matter Don looks scruffy and dirty.
Evil anti-matter John tells good matter John that hes taking his place in the matter world and commands him to trade clothes.
Evil anti-matter John takes the chain from around his neck and places it around good matter Johns neck. Evil anti-matter John
then unzips his uniform and we see a deep scar around his neck from the shackles. Evil anti-matter John leaves good matter
John with evil anti-matter Don so that he can imprison John.
Will and the Robot appear on a pathway between time and space. The pathway appears to be floating and a foggy mist seems to
emanate from it. They finally reach the door to the anti-matter universe. The door is outlined by fire for a few seconds then
the fire dies down. Will and the Robot walk through and discover that they cannot move. There are huge white boulders
everywhere. Suddenly the boulders move and leave the scene. After the boulders are gone, Will and the Robot can move and they
find a pathway of small white leafless trees and begin to walk down it. Suddenly Will and the Robot come across John on the
pathway. Will is overjoyed to see his father and runs into anti-matter John's arms and hugs him. Will and John walk down the
pathway hand-in-hand, but Will does not realize that it is evil anti-matter John and that his real matter father has been
When anti-matter John, Will, and the Robot all return to the matter universe everything seems happy and back to normal. However
the Robot seems to distrust John. The family wants to have a party to celebrate Johns return, but anti-matter John becomes
oddly serious and says that theres no time for it they need to get the Jupiter-2 ready and have it space worthy immediately.
Don and Maureen try to convince John to allow the children to have the party. John thinks for a moment and decides to go ahead
and let the children have the celebration. At the party strange things happen to people who get too close to the anti-matter
John Robinson. Both Will's and Don's watches start working backwards and Penny's tape machine plays songs backwards.
After the party, anti-matter John wants everyone working to get the Jupiter-2 back in space. John has an angry confrontation
with Dr. Smith. Maureen attempts to calm him down, but John angrily turns on Maureen and tells her if he wants her opinion,
he will ask her for it. Hurt, Maureen turns away and follows the girls inside the Jupiter-2 to prepare for work. Don tells
John that he was way out of line with Maureen. John admits he was wrong, but the only reason that he wants the Jupiter-2 up
and running is because he is worried about his family. Don seems convinced with Johns story. However, Will eyes John
strangely and doesnt seem to trust his father as he used to do.
That night Will has a strange dream of his father screaming out for his help. Will goes to the main deck of the Jupiter-2 where
the Robot is waiting. Will tells the Robot about his dream and his doubts about his father. The Robot says that the John they
have is Will's father, but at the same time, he is not. The Robot explains that the John that they have with them is the
anti-matter John and that he is evil. Will and the Robot decide that they will both return to the anti-matter world to find
the real John. However, Will and the Robot are unaware that the evil anti-matter John had secretly listened to their entire conversation.
The Robot activates the nuclear motors while Will stands between the two machines. Before the Robot can join Will, anti-matter
John strikes the Robot with a steel pipe and he falls down. Will disappears to the anti-matter world. Anti-matter John runs
between the two atomic motors and also disappears to the antimatter world. Since there are two Johns in one world, lightning
storms are brewing in both. Due to all the commotion, Don and Dr. Smith rush outside and find the fallen Robot lying next to
the nuclear motors. They right the Robot and he explains everything that has happened. The Robot moves to stand between the
motors and tells Don to turn them on. Dr. Smith dashes to the Robot to argue, and when Don turns on the motors, both Dr. Smith
and the Robot disappear. Dr. Smith and the Robot are both now in the anti-matter world. They began to follow the pathway of
leafless white trees.
Will is already far ahead upon the leafless white tree pathway. Will hears the anti-matter John coming after him and begins
to run. As Will runs down the pathway he is stopped by anti-matter Don who is blocking the path. Will turns around and
anti-matter John is right behind him. Both anti-matter John and anti-matter Don take Will to a cave that is guarded by a red
alien monster. Inside the cave are the anti-matter Robot and the matter John. Will sees that they have his father imprisoned
inside a cage hanging from the ceiling.
John tells them to leave Will alone and allow him to go back to the matter world. Anti-matter John says that he is planning
to take Will back with him. Will refuses saying he will not leave his true matter father. Anti-matter Don wants to know when
he will trade places with matter Don. Anti-matter John tells him to be patient. then anti-matter John leaves, forcing Will to
go with him. It is also quite obvious that anti-matter John never plans to exchange anti-matter Don with matter Don.
The Robot and Dr. Smith are moving up the pathway of leafless white trees. Anti-matter John hears them coming from the
opposite direction, covers Wills mouth with his hand, and hides them both until the Robot and Dr. Smith have walked by.
Anti-matter John and Will continue to the misty pathway that lies between the two worlds.
Inside his cage in the cave, matter John starts a fight with anti-matter Don and eventually knocks him out and escapes from
his cage. Dr. Smith and the Robot show up and the Robot knocks out the red alien monster guard. John leaves to confront his doppelganger. The Robot confronts his anti-matter self. The anti-matter Robot is encaged because of his horrible ways. He
calls the Robot a punk and tells him to go away. The Robot leaves and the anti-matter Robot sings Swing Low, Sweet Chariot.
Will tries to tell the anti-matter John that he cannot get away with what he is doing. Anti-matter John says that there is
nothing Will can do about it. Will tells the anti-matter John that he is not his father. However, the anti-matter John insists
that he is. Anti-matter John basically tells Will that hes a only a little boy and that there is really nothing he can do
about it. Anti-matter John then continues to force Will along the pathway.
Anti-Matter John eventually finds the misty pathway in between worlds and begins to run after anti-matter John and Will. Matter
John finally catches up to them and yells Wills name. Anti-matter John pushes Wll behind him and confronts the matter John.
They begin fighting a knock 'em sock 'em fight-out. However, matter John wins when he throws anti-matter John off the pathway
between universes. The real John and Will are reunited and they hug-it-out. Now all the family is reunited at the Jupiter-2.
The real John is busy hugging-it-out with his entire family. The episode ends with Dr. Smith claiming to have saved the
day (as usual).
Notes: This is said to be a favorite of both Guy Williams and Mark Goddard due to their dual roles. The anti-matter
John Robinson is supposed to be evil. Whatever he had done in his world, he was punished by being chained and imprisoned.
However, everyone is supposed to have an anti-matter duplicate, but we don't see this with Will, Penny, Judy, Maureen, or
even Dr. Smith. Perhaps their alternate selves weren't bad enough to warrant imprisonment so they're not seen. Certainly,
Dr. Smith's opposite self had to have been good.
We do see two other examples....anti-matter Don and anti-matter Robot. Don's opposite truly seems sinister and evil...almost
nasty in appearance. The Robot's opposite just seems like he's fallen upon hard times rather than being truly evil. However,
it is anti-matter John who is most baffling. He might have been evil, but he was just as smart at the matter John Robinson.
The same can't be said of anti-matter Don. Although anti-matter John has a temper and is at times short with his family, he
often appeared to care about them. This is seen when anti-matter John first sees Will and wraps his arms around Will and
embraces him. Also anti-matter father and matter son walk hand-in-hand down the pathway in the antimatter world. Anti-matter
John is also seen embracing wife, Maureen and daughters, Judy and Penny. While it's true that anti-matter John could have
been pretending....one does not know this for sure. He seems sincere when he embraces Will...then holds hands with him.
He also appears sincere when he embraces his wife and daughters.
One can only guess that anti-matter John had an anti-matter wife and children of his own....and truly cared for his matter
family as well. Anti-matter John had several chances to destroy Will, who kept threatening that he would tell the family
that he was the wrong John Robinson. However, anti-matter John never even considers this. Also, Will tells the anti-matter
John that he is not his father...however, anti-matter John insists that he is Will's father. Later when matter John
confronts anti-matter John on the pathway between worlds...we see antimatter John push Will behind him in an effort to
protect Will. Could this evil antimatter man actually feel a type of love towards his matter family? It would appear so.
There really is a such thing as anti-matter. Scientist have been able to produce anti-matter in very small quantities, and
it doesn't last long in the our matter world. However, if a large portion of matter coincided with a large portion of
anti-mattter...this would cause an enormous explosion. If anti-matter John had really come to the matter world, he wouldn't
last long...for he'd explode in our matter world. It would also have been impossible for Will to hold hands with his
anti-matter father, for one was matter and the other anti-matter. This would have also produced a huge explosion. As of
current scientific facts, matter and anti-matter cannot coexist together.
Mark Goddard and Bill Mumy have cited this as among their favorite episodes. When Don and Will head back to the ship during
the storm at the end of the first scene in Act One, they walk towards the camera with the camera centering on the Robot, the
take ending with a close-up of the Robot's panel. The shot is not in focus but the lettering on the buttons can be seen.
If the Anti-John Robinson is able to just pull the chain collar off his neck any time, then why hasn't he done it long before
now? And when he forces the real John to exchange clothes with him, why does Anti-John put the collar on John before he has
had a chance to take his shirt off? That would make it impossible for John to take his shirt off.
At the end of the climactic fight scene, when the stunt man falls off the bridge, you can see the dust from the mattress that
he falls on.
Anti-matter and matter annihilate each other upon contact. What would be more plausible is that this involves an alternate
universe as posited by the Many-Worlds interpretation of quantum mechanics.
The prop book that is supposed to contains description of weird, unexplained legends of the past is a religious work, as
evidenced by this image of the page that appears before the one with the Shadow World graphic.
When Will and the Robot enter the Anti-Matter world, the shadows of stage hands can be seen moving the large rocks.
Why does the Robot develop a stutter when he enters the Shadow World?
When trying to block out the sound of the moving rocks, Robot puts his hooks up to his bubble as a person would put hands up
to their ears. Does this actually block out the noise?
When Will goes back to the Anti-matter world in search of his father, why does the Anti-John pursue him? It would make more
sense for Anti-John to stay behind and make up an excuse as to where Will is and then escape from the planet in the Jupiter-2.
What is the devil-looking creature in the prison cave on the Anti-matter world? Is that supposed to be symbolic of the fact
that the Anti-matter world is evil?
Why does Anti-Robot say this is opposite world when speaking of his own dimension? If he lived there all his life, one would
think that from his point of view, his world would be the real one and our world would be the opposite.
Why doesnt the Anti-Robot try to trick the real Robot into helping him escape and get to the real world?
Why didnt we get a glimpse of the Anti-Smith? If he was a proper opposite, he would have been a great guy! Honest, loyal,
brave, hard-working, kind, generous... of course, with qualities like that he most likely got killed off rather quickly in
the nasty Shadow World.
Shadows are visible on the backdrop during several of the lightning flashes.
