Miller's Crossing

A typically oddball take on the gangster movie from cult directors the Coen brothers.

Crime boss Leo (Albert Finney) is asked to kill a chiseler who's moving in on someone else's action, only to discover that his target is the brother of his girlfriend.

However, his girlfriend is two-timing Leo with his gambler friend Tom (Gabriel Byrne), who is also ordered to kill the chiseler after he joins a rival faction.
