Bill Mumy

Biography: One of the best child actors of the 1950s and 1960s, freckled-faced Billy Mumy performed with a directness and sincerity that put many an adult performer to shame. Before he was even ten years old, Mumy had played two of the most unforgettable juveniles in TV history: malevolently telekinetic Anthony Fremont on the 1961 Twilight Zone episode "It's a Good Life," and the pistol-toting protagonist of "Bang! You're Dead," an incredibly suspenseful 1962 installment of Alfred Hitchcock Presents, directed by Hitchcock himself. In films from 1963, Mumy's finest cinematic hour-and-a-half was as Erasmus Leaf, an 8-year-old math genius with an all-consuming crush on Brigitte Bardot, in 1965's Dear Brigette. From 1965 to 1968, Mumy appeared as Will Robinson on the popular TV sci-fi fantasy series Lost in Space. As Mumy matured, he found roles harder to come by, though he was given generous screen time in the 1971 Stanley Kramer production Bless the Beasts and Children and was a regular onOne of the best child actors of the 1950s and 1960s, freckled-faced Billy Mumy performed with a directness and sincerity that put many an adult performer to shame.

You're Dead" (one of the components of the 1985 TV revival of Alfred Hitchcock Presents).
