Paul Joseph Schrader is an American screenwriter, film director, and film critic. He first became widely known for writing the screenplay of Martin Scorsese's Taxi Driver (1976). He later continued his collaboration with Scorsese, writing or co-writing Raging Bull (1980), The Last Temptation of Christ (1988), and Bringing Out the Dead (1999). Schrader is more prolific as a director: his 22 films include Blue Collar (1978), Hardcore (1979), American Gigolo (1980), Mishima: A Life in Four Chapters (1985), Light Sleeper (1992), Affliction (1997), and First Reformed (2017), with the last of these earning him his first Academy Award nomination. Schrader's work frequently depicts "man in a room" stories which feature isolated, troubled men confronting an existential crisis.
