- Jeffrey Hunter, The True Story of Jesse James, 1957. Early casting for Frank James - but he would have buried the lightweight Robert Wagner’s Jesse. The following year, they co-starred for In Love and War, 1958.
- Ricky Nelson, Rio Bravo, 1958.
- John Gavin, Psycho, 1960. Alfred Hitchcock’s first choice proved too pricey for the November 30, 1959, start of the low budget, “TV-style” Paramount movie #9401. (Hitch soon dubbed Gavin... “The stiff”)
- Pat Boone, Goodbye Charlie, 1964. Marilyn Monroe-Frank Sinatra-Whitman became Debbie Reynolds-Tony Curtis-Boone. Whitman’s career quickly dissipated into z-schlock and TV guest over the next 40 (quiet) years.
- Charlton Heston, Planet of the Apes, 1967.
- Doug McClure, The Land That Time Forgot, 1974. The US co-producers, AIP refused finance a film with Whitman. So Amicus, the UK end, deep-sixed him from Movie That You Should Forget... Or, The Effects That Time Has Not Been Kind To...
Alex Cord, Inn of the Damned, 1974. Family issues caused Whitman to pass on being Sheriff Kincaid, investigating why the guests at a local hotel checked in, but never checked out. Writer-producer-director Terry Bourke called his Australian film: Hitchcock on horseback.
