Martin made movies on his own, which were mostly comedies. Four of them starred him as "Matt Helm", a spy like James Bond. Martin also appeared in dramatic movies, like "Rio Bravo" and "Airport". When he sang onstage or on television, he always had a cocktail glass with him. Most people thought he was drinking whiskey as he performed. However, he actually drank apple juice the whole time. Offstage, Martin enjoyed Jack Daniels whiskey, and red wine.
