Paul Schrader is in the midst of one of the most illustrious careers in Hollywood history, but much of it seems to have occurred under the radar. He wrote “Taxi Driver” and “The Last Temptation of Christ” and co-wrote “Raging Bull”; he’s directed dozens of films, including “Blue Collar” and “American Gigolo” (which launched Richard Gere as a star), “Mishima” (one of the most ambitious and visionary ever produced by a studio) and “Affliction” (which won James Coburn an Oscar for Best Supporting Actor). Hollywood has a short memory: for his 2013 film “The Canyons” (starring Lindsay Lohan), he turned to Kickstarter for financing.
