Trivia

The casting of Fernando Rey was an accident. William Friedkin had wanted to cast Francisco Rabal, whom he had seen in Belle de jour (1967), but at the time didn't know his name. Only after actor and director met did Friedkin realize Rey wasn't the actor he had wanted. Friedkin ended up keeping Rey after learning that Rabal spoke neither English nor French. See more...
