Casi Casados (1961)

A poor mechanic is conned into taking the place of a wealthy business magnate so the rich man can take off to work on some major wheeling and dealing. Sure enough, the impostor is trapped in a series of circumstances beyond his control that lead him right to the altar. Once he is wed -- or rather, once the rich businessman is unknowingly wed by proxy, the tycoon returns from his trip with the subsequent surprises in store for all concerned.

Casi Casados has a runtime of 75 minutes.
