Kevin Spacey on keeping Keyser Söze’s identity secret

Kevin Spacey tells a fun anecdote from the shooting of “The Usual Suspects” [itunes.com, itunes.de]:
Bryan Singer, who directed that film, had managed to convince every one of the major actors in that movie that they were in fact Keyser Söze. I remember when we screened it for the company of actors, Gabriel Byrne was stunned that he wasn’t Keyser Söze. Went out into the parking lot and had an argument with Bryan Singer. For a half an hour. [Source: Spinoff Online]
