Beginning a career in radio in Illinois in the late '30s, Jackson moved to Hollywood in 1951, where he took up a role as a radio and television manager for Cecil & Presbrey. Jackson moved to film work in 1953, and by 1961, he and fellow showman Robert Patrick, established the distribution company Parade Releasing, for which Jackson produced the English-language version of 'I Bombed Pearl Harbor' (1960, dir. Shue Matsubayashi), which landed him an uncredited role as the dialogue director on the English-language version of 'Monster Zero' (1965, dir. Ishiro Honda) for Henry G. Saperstein's United Productions of America. By the early '70s, his film career was placed firmly in overseeing the ADR for adaptations of foreign-language genre films, working on the U.S. releases of titles including 'King Kong Escapes', 'The War of the Gargantuas', 'Godzilla's Revenge', 'The Retreat From Kiska', 'High Seas Hijack', and 'The One-Armed Executioner'. In 1982, he established the ADR company Showmen, Inc., for which he produced 'Warriors of the Wind', the edited English-language version of Hayao Miyazaki's 'Nausicaä of the Valley of the Wind' for Manson International in 1984.
