The Split (1968)

Synopsis
A pair of crooks conspire to rob the ticket booth at the Los Angeles Coliseum during a Rams game. Before they can perform the heist, the two must find precisely the right henchmen to join them. Each potential gang member must undergo a rigorous test of skill. Thanks to care and precise planning, the caper comes off smoothly and afterward the gang leader (Jim Brown) hides the money in the apartment of his ex-wife (Diahann Carroll). She only agrees to keep the money on the provision that he reform so they can get back together. Unfortunately, the wife's lust-crazed landlord (James Whitmore) busts into her house the next day and tries to rape her. During the struggle he kills her and then takes the loot. Later a crooked cop (Gene Hackman) investigates. Meanwhile, when the gang members learn that the loot is missing, they suspect a double-cross and engage in a huge battle. The cop finds the money and at first keeps it for himself. The head crook eventually figures out that the cop has it and so goes to him to make a little deal. ~ Sandra Brennan, All Movie Guide
