Goofs

Bob can't go back to the Guttmans' that rainy night, and it pours and pours and pours, forcing Leo to agree he stay the night. Next morning when GMA crew arrives, the ground is dry. The stairs are dry to sit on, even at 7:00 am, for the family to discuss how the interview went.

After Dr. Marvin has his breakdown near the end of the movie, the doctor taking care of him in his home believes he has left Leo sedated in the bedroom. He accompanies Fay, Lily, and Bob into the hallway where he gives them instructions. At one point he takes out his prescription pad with the intention of writing, while simultaneously telling them what he intends to prescribe. At the moment the doctor merely touches his pen to the pad, Bob begins to question his choice of medication, causing the doctor to pause and reconsider. He then states that Bob may be right and that he would rewrite the prescription. The problem is that he never wrote anything to begin with as the pad is empty as he walks away from them down the hall.

When Bob goes to sleep, there's no alarm clock, but when Leo comes to wake up Bob next morning, an alarm clock is prominently made visible (showing time as 6).

The photograph of Lily in Dr. Marvin's office changes between the wide shot and the close-up.

During the chicken dinner, the amount of water changes in Siggy's water glass.

Bob recites a poem that ends with I'm schizophrenic & so am I. This implies a split personality, which is a different disease. Schizophrenics have visual & audio hallucinations. Their perceptions change, not their personalities.

In the scene where Dr. Leo Marvin is receiving a traffic ticket from a NH State Trooper, the trim on the Trooper's uniform is yellow/gold. In fact, NH State Police uniforms have green piping on the pockets and epaulets of the shirt, and a green stripe on the outside leg of the pants.

When Marie from Good Morning America (1975) is interviewing Dr. Marvin and Bob, Leo inadvertently calls her "Joan" the first time he speaks to her. Joan Lunden plays/is the home-base correspondent for GMA. Leo had been rehearsing his speech to Joan Lunden all night, but Marie was the interviewer that came to his house. Leo froze up on TV and repeated his rehearsed message even though it was no longer appropriate.

When Leo arrives home after changing his flat tire, he finds his wife has thrown him a surprise birthday party. Instead of singing the usual, "Happy Birthday, dear Leo," the large crowd of guests sang, "Happy Birthday, Leo Marvin." However, the writers may have done this on purpose to be amusing.

When the Good Morning America (1975) crew arrives for filming, the Sigmund Freud bust is on the mantle in the background. When the crew actually begins filming, the bust has been replaced by duck decoy for the full filming sequence.

The film crew is shown trying to decide exactly where and how to shoot the sequence. The shot then follows Bob and Leo outside while the film crew is setting up. It's not unreasonable to think that the crew would move things around to appease their own aesthetic (switching the bust for the duck). They were given plenty of time to do it in (20 seconds of screen time plus however long during the cut).

Gil the goldfish changes species throughout the film.

Bob's boat is obviously being pulled, not sailed.

The closed captions on the DVD misspell "Halcion" as "Halcyon".

The New Hampshire license plates on the Marvins' station wagon are from the 1983 series instead of the 1989 series.

In widescreen versions, the Steadicam operator is reflected in the window of the general store.

A previous contribution states that the Marvin's vehicle plates are from NH, but they're from NYC. Did anyone consider that they'd keep a vacation vehicle at their summer home? The movie never reveals how they arrived at the lake from New York.

The lake is obviously not in New Hampshire as evidenced by the abundance of Longleaf Pine trees, which only grow as far north as southern Virginia (where the lake scenes were filmed).

Leo Marvin lives in New York City and vacations in New Hampshire, yet his family vehicle has NH plates.

After Dr. Marvin throws Bob out of the car and drives away, the boom is reflected in the windshield.

When Bob arrives at Lake Winnipesaukee and steps out of the bus, the boom microphone and a frame with white linen is reflected in the window of the bus.

When Anna picks Bob up on the road and they discuss their issues, Bob never puts on his seat belt, which is inconsistent with the paranoid nature of his character. It's true he doesn't use his handkerchief on the door handle after asking Anna who uses the car, but seat belts are a different matter altogether.

Dr Marvin is identified as a psychotherapist in the movie. Because he's not a psychiatrist, someone who is trained as a medical doctor, he would not be legally able to write prescriptions in the time period in which the movie takes place.

When Bob appears at the Marvins' lake house the second time, he says that he hasn't figured out how to get food yet, but he also says that he is staying at the Guttmans', who own a diner--in which he was waiting for Dr. Marvin's call earlier, so he certainly had been exposed to several avenues for acquiring food.

By the time Bob arrives at Lake Winnipesaukee, Leo is well aware of how desperate Bob is to be around him. But Leo, nevertheless, tells Bob to wait two hours for his call inside the coffee shop that he knows is owned by the Guttmans, who he knows hate him for buying the house and also know where he lives. It should have occurred to Leo that they might disclose where he lives to a talkative guy like Bob.

The weapon over the mantle is incorrectly referred to as a rifle when clearly it is a shotgun. Bob also refers to it as a rifle later. Shotguns are smooth-bores, not rifles.
