Action is a 1980 Italian black comedy directed by Tinto Brass. The film is reminiscent of the director's earlier avant-garde low-budget works such as The Howl and Nerosubianco.

Brass faced many difficulties in Italy due to lawsuits concerning the production of Caligula, so he filmed Action in London in 1979.In the film, an actor with hero syndrome has a nervous breakdown. He flees the town with an actress obsessed with the role of Ophelia, but they end up locked at an mental asylum. Following the suicide of "Ophelia", the actor flees the asylum with an anarchist patient.
