TV's original Will Robinson from "Lost In Space". Bill Mumy was born Charles William Mumy Jr. in San Gabriel, California, USA, on February 1st, 1954. Becoming a child star when he was just six years old on General Electric Theatre, he then progressed to "Alfred Hitchcock Presents" in 1961, in one episode, playing opposite the actress to later become his TV sister on "Lost In Space", Marta Kristen.

He then gravitated to more dramatic roles, one especially which was to become one of his most famous in November 1961, portraying the menacing, Bewitched boy Anthony Fremont in the episode "It's A Good Life" in Rod Serling's "The Twilight Zone", thus also beginning his own long career in science-fiction related TV shows.

During the 1960's Bill continued to appear in most of the most popular TV shows of the day such as, "Disneyland", "Bonanza", "I Dream of Jeannie" cast by Irwin Allen to portray his young space hero, Will Robinson in "Lost In Space" - the role which was to cement Bill Mumy's everlasting fame and recognition with generations of television audiences.

In later years, Bill has continued with his acting, portraying the alien Lennier for many years in "Babylon 5", appearing in an episode of "Star Trek : Deep Space 9", voicing the title-role of "Buzz Lightyear of Star Command" (opposite his "Lost In Space" fellow-actor, Jonathan Harris) and appearing in cameo roles in some movies, one of them in "The Twilight Zone" movie reprise.

However, he has pursued his career in music much more vigorously. As the second half of the alternative/comedy musical group, "Barnes and Barnes" (the first half being Robert Haimer), since the early 1980's his involvement in bands such as "America" and writing and performing his own music both with other groups and solo, Bill has carved out a new career for himself. He is an extremely talented musician playing guitar, bass, keyboards, banjo, mandolin, harmonica, percussion and sings.

Bill has written for Marvel Comics, Dark Horse Comics, DC Comics and Pocket Books. The stories he co-wrote include well-known titles as "Spider-Man", "The Hulk", and "Clive Barker's Hellraiser." He co-wrote a STAR TREK trilogy "Return of the Worthy", and was a creative consultant and writer to the "LOST IN SPACE" Innovation monthly comic. He also has written for DC comics, "Aquaman", "The Spectre" and "Star Trek".

His current writing projects include the feature film, "Overload" and a fantasy novel co-written with Angela Cartwright (his TV sister Penny Robinson in "Lost In Space"), "Realms Of Majik: The Pocket in Reality". His short stories, "The Black '59" and "The Undeadliest Game" appeared in Pocket Books "Shock Rock" Volumes 1 and 2. Both have been printed globally in many languages. Bill has also written for animation, most recently an episode of the sci fi series, "Roswell Conspiracies". He has also written episodics for NBC's series, "Sunshine", USA network's "Swamp Thing", as well as scripting an unfilmed episode of "Babylon 5". He co-created and wrote the Marvel Comics series' "The Comet Man", "The Dreamwalker" graphic novel, and Dark Horse Comics' "Trypto, The Acid Dog" with Miguel Ferrer.

Bill Mumy's latest project (being filmed presently in Vancouver, BC, Canada), is once again portraying the (now adult) Anthony Fremont in a sequel called "It's Still A Good Life", on TV's new "Twilight Zone" series.

His daughter Liliana is now following in her father's footsteps, also acting, with roles such as in "Santa Clause 2". He and his wife Eileen, also have an older son, Seth.
