Transcription: another great challenge as an actor to do a film that takes place in real time so that the clock starts ticking at 12 noon and by 1.30 it's over with. And to shoot that hour and a half or hour and 40 minutes, whatever it is, over a span of about two and a half months So the challenge is the continuity of the thing, the emotional continuity and psychological continuity. When I read the script it really reminded me of an old Hitchcock thriller doing 200 miles per hour.
