Big break
Bill Mumy's career took off when he was picked to play Will Robinson, a 9-year-old, in Lost in Space, the science fiction series CBS broadcast from 1965 to 1968. His character appeared in 84 episodes.
First role
Mumy started working professionally when he was seven years old. Since then he has appeared in over four hundred TV episodes, eighteen films, commercials, and many voiceover projects.
Behind the camera
In 1996, Mumy helped create and write Space Cases, a show on Nickelodeon whose themes resembled those of Lost in Space.
Getting ready for a role
Mumy played Kellin on Star Trek: Deep Space Nine in 1998 and was glad the character was human, since playing Lennier on Babylon 5 had required prosthetic makeup.
