Breaking Point is a 1976 Canadian-American crime drama film starring Bo Svenson, and featuring Robert Culp in a supporting role, produced and directed by Bob Clark.
Former Marine and Judo instructor Michael McBain witnesses a murder. Initially reluctant to identify the two culprits, he is eventually persuaded by Lieutenant Frank Sirriani, who believes their trial will lead to the arrest of Vincent Karbone, a construction magnate in Philadelphia and suspected leader of one of the city's most notorious Mafia gangs. McBain testifies despite intimidation; however, to Sirriani's surprise, the defendants refuse to name Karbone and reject a plea-bargain.
McBain and his family try to return to their ordinary lives. Instead, Karbone plans to kill McBain and his family, who are all put into witness protection (a program that was newly introduced in the US in 1971) and moved to Toronto. The family's new identity is compromised, though. Learning of his sister Diana's fiancé Ted Buchanan's murder, McBain returns to Philadelphia to take on Karbone himself, eventually killing him and neutralizing the threat to his family's life.
Daily Grindhouse called the film "frequently dull, often sloppy, and absolute generic movie" that only becomes "serviceable" and "fun to watch" in the third and final act of the film.
