In 1924 Chicago, Artie Strauss and Judd Steiner are friends and fellow law students who both come from wealthy backgrounds. They have few true friends as they believe all their contemporaries are intellectually inferior. Within their relationship, Artie is the dominant and Judd the submissive who says he will do whatever Artie tells him. Although Judd acts intellectually arrogant to others, he also shows signs of weakness and reticence most evident to Artie. Part of their goal in life is to experience how it feels to do everything. As such, they plot to commit what they consider the perfect crime - a kidnapping and murder - not only so that they can experience the sense of killing for killing's sake, but also taunt the law with the knowledge of it and their superiority after the fact. They believe their crime is above the law. Their murder of young Paulie Kessler is not so perfect, with evidence at the scene uncovered by one of their law school colleagues, Sid Brooks, who also works ... Written by Huggo
I don't know why I'm so attracted to this vulnerable weirdos. From Anthony Perkins as Norman Bates in Psycho to Colin Firth as Adrian Leduc in Apartment Zero, darkness and a fragility that is part of the unbearable suspense. Maybe I'm in need of professional attention but I don't think so. What attracts me is by the undeniable innocence behind the horror and that has a lot, if not everything, to do with the actors playing them. Look at Anthony Perkins in Psycho! 57 years ago and it still looks and feels kind of revolutionary or Colin Firth in Apartment Zero, the character is so unique and real that you can see it a thousand times and always find some new extra something, then Dean Stockwell in Compulsion. He plays a monster, a sick, pathetic prince of a man. Yes all of that. The humanity of the actor makes the monster human and we can't dismiss him, he doesn't allow us. Orson Welles has a great entrance into the film and E.G Marshall is superb as per usual, it is the rest of the cast who seem a bit dated, specially when sharing the frame with the extraordinary Dean Stockwell
