Scarface (1983) ending / spoiler
Tony Montana kills Manny for marrying his sister. After Tony goes home and snorts a mountain of cocaine, his sister goes crazy and tries to kill Tony. She shoots him in the leg but a Columbian assassin shoots Tony's sister and Tony kills the assassin. Tony watches as all of his men are killed and Sosa's men invade his mansion. Tony blasts through his doors with a grenade launcher attachment and guns down many Columbians while being shot in the meanwhile. He takes the bullets without pain (because of all the cocaine he snorted), but he finally succumbs when an assassin shoots him in the back with a shotgun.
