'Taxi Driver' Oral History: De Niro, Scorsese, Foster, Schrader Spill All on 40th Anniversary - Hollywood Reporter

PAUL SCHRADER (screenwriter) I had a series of things falling apart, a breakdown of my marriage, a dispute with the AFI, I lost my reviewing job. I didn't have any money and I took to drifting, more or less living in my car, drinking a lot, fantasizing. The Pussycat Theater in L.A. would be open all night long, and I'd go there to sleep. Between the drinking and the morbid thinking and the pornography, I went to the emergency room with a bleeding ulcer. I was about 27, and when I was in the hospital, I realized I hadn't spoken to anyone in almost a month. So that's when the metaphor of the taxi cab occurred to me — this metal coffin that moves through the city with this kid trapped in it who seems to be in the middle of society but is in fact all alone. I knew if I didn't write about this character I was going to start to become him — if I hadn't already.
