What about Bob? (1991)

Continuity mistake: When Bob is in the coffee shop waiting on the call from Dr. Marvin he chases an older man away from the phone. The rope for the fish jar hanging around his neck is twisted around once or twice. The camera cuts away from him then back to him and then the rope is twisted around seven or eight times. (00:27:15)

Continuity mistake: In the scene where Dr. Marvin tells Bob to "take a vacation from his problems", there are white sailboats on the lake in back of Bob but when the scene shifts back to Dr. Marvin, the boats are gone, then they once again, magically reappear.

Trivia: Bill Murray and Richard Dreyfus did not like each other in real life, and were actually hostile to each other on several occasions during the shooting. This real-life hostility may have actually fed the on-screen chemistry of their characters.

Trivia: Julie Hagerty plays Kathryn Erbe's mother in the film, even though in real life she's only 10 years older than Erbe.

Mr. Guttman: Hello, Dr. Marvin. The house looks good.
Mrs. Guttman: Burn in hell, Dr. Marvin.

Dr. Leo Marvin: You understand, don't you? There's no other solution. You won't go away.
Bob Wiley: I will.
Dr. Leo Marvin: No, you won't. You're just saying you will! But then, after I don't kill you, you'll show up again. And you'll do something else to make everyone in my life think you are wonderful and I'm a schmuck. But I'm not a schmuck, Bob, and I'm not going to let you breeze into town and take my family away from me, just because you're crazy enough to be fun.

Bob Wiley: Baby step to four o'clock. Baby step to four o'clock.
