Going Berserk is a 1983 American-Canadian comedy film starring John Candy, Joe Flaherty, and Eugene Levy and directed by David Steinberg.

[1] John Bourgignon is an amiable chauffeur and would-be drummer who is engaged to the daughter Nancy, of an extremely disapproving United States congressman Ed Reese.

As the wedding date approaches, John's sleazy film-director friend, Sal DiPasquale, blackmails the senator into allowing him to record the ceremony.

John has assorted misadventures, including being handcuffed to a dead man, running afoul of a motorcycle gang, and getting brainwashed by an aerobics cult that wants him to assassinate the congressman.

The New York Times review stated, "John Candy is easily the funniest thing in Going Berserk, an affably stupid comedy that's saddled with too much plot and that hasn't nearly enough energy to go with it.
