On June 3, 1968, Valerie Solanas, author of the "shock-feminism" classic SCUM Manifesto and a regular of the Factory (Warhol's studio), entered the studio and fired three shots at Warhol, nearly killing him. Although the first two rounds missed, the third passed through Warhol's left lung, spleen, stomach, liver, esophagus, and right lung. Solanas then turned the gun on a companion of Warhol, Mario Amaya, injuring his thigh. Although Warhol (barely) survived these injuries, he never fully recovered. Solanas turned herself in to the police, and was charged with numerous offences, including attempted murder. After pleading guilty she received a three year sentence. Warhol refused to testify against her. Solanas later explained that "Warhol had too much control over my life." In 1966, Solanas wrote a play entitled 'Up Your Ass', about a man-hating prostitute and a panhandler. In 1967 she asked Warhol to produce her play, and he was fascinated enough by the title of the play to accept the script for review. He was unimpressed by the content, however, and did not bother to contact her again. Later in 1967 Solanas began to telephone Warhol demanding he return the script of Up Your Ass. Warhol admitted he had lost it, at which point she began demanding money as payment. Warhol ignored these demands. However, he did employ her for minor roles in two of his movies of the time, but Solanas began to believe that her difficulties achieving financial success were exclusively due to Warhol. The story of Valerie Solanas was made into the 1996 movie I Shot Andy Warhol starring Lili Taylor and directed by Mary Harron. Warhol's friend Lou Reed never forgave Solanas for the attack. In 1990 he recorded the album Songs for Drella with fellow Velvet Underground alumnus John Cale, which contained the song "I Believe". In it, Reed sang "I believe/I would've pulled the switch on her myself." In other songs on the album, Reed expresses his regrets about not having paid a lot of attention to Warhol in the time before his death. Warhol himself ultimately forgave Valerie for shooting him and later satirized the whole event in a subsequent movie of his, calling a group similar to Solanas' S.C.U.M. (Society for Cutting Up Men), P.I.G. - Politically Involved Girlies.
