The In-Laws is a 1979 American action comedy film starring Alan Arkin and Peter Falk. The film was remade in 2003, with Michael Douglas, Albert Brooks, Candice Bergen and Ryan Reynolds.

Plot

The daughter of mild-mannered, Manhattan dentist Sheldon Kornpett (Arkin), and the son of businessman Vince Ricardo (Falk), are engaged to be married. At an introductory dinner party, Vince tells hysterically exaggerated tales of his "consulting" work in 1954 Guatemala (a subtle CIA reference). Sheldon senses something suspicious right away, and this suspicion gets stronger for both Sheldon and the audience as the movie progresses. Ultimately, Vince dupes Sheldon into joining a rogue CIA plot to rob the U.S. Treasury on behalf of an insane Latin-American dictator (played by Richard Libertini) who talks to a face painted on his hand (à la Señor Wences).
