Serge Houde (born February 16, 1953) is a Canadian film and television character actor. He is best known for his role in Jon Cassar's Emmy-nominated miniseries The Kennedys playing the notorious Chicago mafia boss Sam Giancana opposite Tom Wilkinson and Barry Pepper. GQ's Tom Carson said Houde's performance was "a terrific Sam Giancana (Serge Houde, and where has this formidable actor been all of Martin Scorsese's life?). It will probably set off Camelot guardians' alarm bells to hear that Giancana, the Chicago Mob boss, appears at all—and tête-à-tête with papa Joe, who's committing hubris's fatal error by negotiating with him." Houde began acting at age 35, and he has over 160 film and TV productions to his credit.
