Billy Gray on AllMovie

Juvenile actor Billy Gray began appearing in movie bit parts at age 5. The best-remembered of his 1950s film appearances were in The Day the Earth Stood Still (1951) as the inquisitive son of Patricia Neal; On Moonlight Bay (1952), as Booth Tarkington's Penrod; and The Seven Little Foys (1955), in which he played the teenaged version of future film producer Bryan Foy. Billy was slated to portray Tag Oakley on the 1953 TV western Annie Oakley, but instead opted to co-star as Bud Anderson on the long-running Father Knows Best (1954-60). His appearances in film and on television became sporadic after the 1950s.
