Almost ten years passed before Clément directed a feature but his French Resistance film, La Bataille du rail (1945), gained much critical and commercial success. From there Clément became one of his country's most successful and respected Directors, garnering numerous awards including two films that won the Academy Award for Best Foreign Language Film, the first in 1950 for The Walls of Malapaga (Au-delà des grilles) and the second time two years later for Forbidden Games (Jeux interdits). Clément had international success with several films but his star-studded 1966 epic Is Paris Burning?, written by Gore Vidal and Francis Ford Coppola and produced by Paul Graetz was a costly box office failure.
