Man-Trap (1961)

Helmed by Edmond O'Brien, this slick crime thriller stars Jeffrey Hunter as naïve Matt Jameson, whose Korean War pal Vince Biskay talks Matt into helping commandeer nearly $4 million from a Central American dictator. After Vince is wounded in a gun battle as they're making off with the loot, the duo holes up at Matt's house -- where his boozy, promiscuous wife puts the moves on Vince.
