A Fish Called Wanda (1988)

In London, four very different accomplices join forces for a jewel heist involving a valuable collection of diamonds. Once the job is in motion, their uneasy partnership turns into a scramble for the loot, with each trying to outsmart and double-cross the others. Their schemes grow more complicated as they attempt to mislead the proper barrister Archibald Leach, who becomes entangled in the pursuit.
