Kill or be Killed [1950] [DVD]

Laurence Tierney is an engineer and architect in Brazil. He wants to be paid for installing an air-conditioning unit in a dive, but he's put off. Before you know it, he's been accused of a murder, shot at by the police, swum underwater for a couple of hundred yards with a bleeding wound, and been rescued by concert pianist Marissa O'Brien who's about to go find some peace in the jungle. He invites himself along, lest the police's aim improves with practice, and finds himself designing a new house for George Coulouris, who's talking with a German accent.
