Mr. Randolph and his wife were called before the House Un-American Activities Committee in 1955 but refused to testify. He remained blacklisted from film and television work until the mid-1960s, returning to work in the science-fiction film Seconds in 1966. That film, directed by John Frankenheimer, starred Rock Hudson and also featured Will Greer [sic] and Jeff Corey, who had also been blacklisted.
