American Boy: A Profile of Steven Prince is a 1978 documentary directed by Martin Scorsese. Its subject is Scorsese's friend Steven Prince, best known for his small role as Easy Andy, the gun salesman in Taxi Driver. Prince is a raconteur telling stories about his life as an ex-drug addict and a road manager for Neil Diamond. Scorsese intersperses home movies of Prince as a child as he talks about his family. When talking of his years as a heroin addict, Prince tells a story about injecting adrenaline into the heart of a woman who overdosed, with the help of a medical dictionary and a Magic Marker. This story was re-enacted by Quentin Tarantino in his screenplay for Pulp Fiction. Prince also tells a story about his days working at a gas station, and having to shoot a man he caught stealing tires, after the man pulled out a knife and tried to attack him. This story was retold in the Richard Linklater film Waking Life.
