Winner of the 1976 Palme D'Or at Cannes and later cited as the best film ever to win the fest, Taxi Driver is the pitch-black urban drama that cemented the bond between Martin Scorsese and Robert De Niro. The pair seem to goad each other to daring new heights and depths throughout this hellish tale of a New York cabbie for whom ennui becomes a violently motivating force. The only thing illuminating this sewer of darkness is the artistry of its makers, including an Oscar-nominated Jodie Foster as the barely pubescent prostitute Iris. In a new 35 mm print.
