Trivia

Thanks to good financial investing, he had amassed a personal fortune of $100 million as of 1998.

Initially studied both law and drama at Los Angeles City College after he was discharged from the United States Army in 1948.

He was considered for the role of Bart Maverick on the television Western Maverick (1957), but Jack Kelly was chosen for the role.

Was close friends with David Janssen.

Alfred Hitchcock considered him, along with Cliff Robertson, Robert Loggia and Tom Tryon, for the role of Sam Loomis in Psychose (1960), but the role went to John Gavin.

In 1960, MGM toyed with the idea of doing an all-male remake of Femmes (1939) which would've been entitled "Gentlemen's Club." Like the female version, this would have involved an all masculine cast and the plot would have involved a man (Jeffrey Hunter) who recently discovers among his comrades that his wife is having an affair with another man (Earl Holliman) and after going to Reno to file for divorce and begin a new life, he later finds himself doing what he can to rectify matters later on when he discovers that the other man is only interested in money and position and he decides to win his true love back again. Although nothing ever came of this, it would have consisted of the following ensemble had it did: Jeffrey Hunter (Martin Heal), Earl Holliman (Christopher Allen), Tab Hunter (Simon Fowler), Lew Ayres (Count Vancott), Robert Wagner (Mitchell Aarons), James Garner (Peter Day), Jerry Mathers (Little Martin), James Stewart (Mr. Heal), Ronald Reagan (Larry), Troy Donahue (Norman Blake), and Stuart Whitman (Oliver, the bartender who spills the beans about the illicit affair).
