Biography
Roccuzzo's parents were both actors working in an East Coast Italian repertory, inspiring him to take the acting career path at an early age. When Mario was 10, his father died and his mother relocated the family to California, where he began taking night classes for acting, first with Jeff Corey, then Corey Allen. In 1960, at the age of 20, he appeared, uninvited, in the office of director John Frankenheimer of Columbia Studios, asking for a chance to audition for whatever film he was making next. This led to his first big break, playing Diavolo in the film The Young Savages.

Next, he played Nicky on the top television show, The Untouchables. He initially became typecast in "bad guy" roles, but this gradually expanded to general roles in police/crime shows, both drama and comedy.
