Maidstone is a 1970 American independent drama film written, produced and directed by Norman Mailer. It stars Mailer and Rip Torn.
Famous film director Norman Kingsley (Norman Mailer) runs for President while working on his latest film project. His brother Raoul (Rip Torn) continues to cling to him for his money.
The film is now famous for the improvised fight between Norman Mailer and Rip Torn. As the camera rolled, Torn struck Mailer in the head with a hammer, intending to "kill his character." Mailer's scalp opened up, and a vicious fight ensued. With the camera still rolling, Torn energetically strangled Mailer until the fight was broken up by Mailer's wife Beverly and Mailer's wailing children. During the melee, Mailer bit off a small chunk of Torn's ear. The fight, in which the actors called each other by their real names, made it into the film.
