Revealing mistakes: When Chris is visiting the doctor who buys his last machine, the x-ray hanging in the background is upside down. The x-ray is of an abdomen. The pelvis and bladder should be at the bottom, it is at the top.

Anachronisms: Several times during the movie, reference is made to people with "Pac Bell" (Pacific Bell) pensions. In 1981/82 when the events in this movie took place, PAC BELL did not exist. "Pac Bell" was one of the "baby bells" created by the court ordered divestiture of AT&T in 1984. Prior to that, the official name of the company was "The Pacific Telephone & Telegraph Company", so anyone retiring back then would have had a Pac-TELL pension, not a Pac-BELL pension.

Anachronisms: When Chris gets into the cab with Mr. Twistle, there is a UPS truck with the 2004 Livery painted on it. The film is set in 1981.

Continuity: When Chris is chasing after Hippie Girl in the BART station, he looks from the gate area down to the train platform. Hippie Girl is standing next to a BART train that displays BART's "#1 Transit System in America" decal just to the left of the door. After he runs down to the platform and bangs on the closed door of the train, this decal is missing and only a slight shadow remains and may have been removed post-production. Additionally, this award was bestowed in October 2004, so it is also anachronistic for a story taking place in 1981.

Anachronisms: The original Rubik's cube did not have the logo on the center white square. This was added much later.

Continuity: When Chris and son are sitting in the BART station, the seat alternates between a long one and a short one. Also, they alternate between being close together and being far apart.

Continuity: When Chris is in the cab with Mr. Twistle solving the Rubik's Cube, there is a decal for a local radio station (KMEL) on the cab window behind him in the interior shots, but there is no such decal in the exterior shot.

Anachronisms: At Candlestick Park, there is a 49ers logo that was not introduced to the team until 1996. The pictured logo has golden ends and a thicker black edge than the appropriate 49ers logo for 1981.

Anachronisms: In 1981, the seats in BART trains were tan, not blue.

Anachronisms: The lettering and logo that appears on the Togo's cup that is seen when Chris is making cold calls during the internship did not appear until the late 1990s/early 2000s.

Anachronisms: When Chris and little Chris are in the Glen Park BART station, a BART train is seen departing the system, with a "C" type car on the end (a cab car with a flat face rather than slanted). Such cars did not start operating on BART until the mid-'80s.

Continuity: When Chris gets into the car after the football game he doesn't have his bone scanner with him, but in the next shot it is there, sitting on his lap.

Miscellaneous: At the subway, Christopher is sitting on the bench with his legs crossed, showing his sneakers' soles; they were clean, as if they were brand new.

Anachronisms: f7 When Jay Twistle is giving Chris his phone number and Chris can't find a pen to write down the number, Jay states the phone number with ten digits (area code first). But in 1981, local numbers didn't require ten digits - only seven.

Errors made by characters (possibly deliberate errors by the filmmakers): When little Chris' mother carries him in the bedroom and puts him in bed, he is supposed to be asleep, however, he lifts both of his legs up so as not to hit the side of the bed.

Continuity: When Chris and Christopher are collecting their stuff after being kicked out of the hotel room, Christopher picks up his basketball in a grocery bag. The next time he is seen, he is carrying a garbage bag.

Crew or equipment visible: In one scene, Chris enters the day care center to pick up his son, while the camera remains outside. The cameraman and camera are clearly visible in the window reflection.
