Albert Brooks starred and also co-wrote the script with Monica McGowan Johnson. He plays Robert, a Hollywood film editor, who is in a roller-coaster of a relationship with Mary, a bank executive. The film pretty much drops in on one go-round of what is clearly there standard cycle of breaking up and falling madly in love again.
It's quite a good film. Brooks is on the likable side of neurotic, and Kathryn Harrold as Mary is quite charming. James L. Brooks plays the director of the film that Robert is editing (He later cast Albert Brooks in Broadcast News.), and Bruno Kirby plays Robert's co-worker, Jay.
The film is full of memorable scenes, including a bit of an extended sequence with Robert at home after he takes Quaalude's that is pure gold and quite a bit more underplayed than the Quaalude scene in Scorcese's The Wolf of Wall Street.
It was interesting to watch this film in the context of the way films and television tackle relationships today - it feels a bit of a precursor to modern relationship comedies. The humor can be subtle and sometimes requires patience but it can really pay off. It's a well-paced film, too. I heard somewhere that - of all people - Stanley Kubrick was a big fan of the film!
I guess the one thing that really stood out for me is that these two people really had nothing in common. Why would Mary want a guy who seems sweet but is really just obsessing about her? Once he gets that white picket fence and her behind it, to what will his obsessions turn?
