Revealing mistake: When Donovan witnesses a fatal traffic accident on a rainy night, he suffers a mild heart attack and collapses in the street. Although he's lying on his back, unprotected from the downpour, surrounded by rain striking the pavement in both foreground and background, closeups show that no rain strikes his face, his felt hat, or his clothing. (00:12:20 - 00:12:50)
Continuity mistake: At the start of the film, when the bus driver helps the man in a wheelchair onto the bus, his hat disappears then reappears. (00:05:00 - 00:06:00)
Continuity mistake: The designated Pope has just been visited by a physician. Three cardinals want to take a stroll outside for some sweets and arts. One of the cardinals stands and rebukes them; you can see that the cross on his chest has its chain caught in a button of the vest. During the rest of the scene the chain is caught in that button in the closer views and is loose in the wider angles. (00:23:50)
Continuity mistake: In the opening scene, there are spectators and the camera zooms in on a man and woman with a Rottweiler standing next to the woman. There is a glimpse of two people past the dog. The camera briefly shifts to show a woman (Sonny) walking toward the front door, then returns to the spectators. The Rottweiler (presumably the same dog) is now standing near the left side of a different man (and is not next to the woman). (00:02:02)
Revealing mistake: When Anna's looking at her reflection in the mirror she starts rubbing her face vigorously. Look at her right cheek and you'll it's red before she rubs, result of multiple takes.
Continuity mistake: In two scenes featuring close-ups of the fireplace days apart, the same logs are burning.
Continuity mistake: When Frisson is giving the adder to the girls, the adder is going to go leave the jar through the hole but in the following shot, it is resting at the bottom.
Continuity mistake: Jacob's phone appears first behind the laptop and, in the next shot, right next to it. (01:04:30)
Factual error: When Mitch Albom is with Rabbi Albert Lewis in his rabbinical office/study they discuss an empty folder on the rabbi's bookcase labeled "God". Religious Jews as this rabbi was, know not to spell out the deity's name, but write it as "G-d" instead.
Factual error: When Andy is headed to Mr. Simon's house, a white 90s Lincoln Town Car can been seen in the background, out of place for the 1965 setting. (01:31:45)
Continuity mistake: In the scene in the kitchen when Helen is telling Joe that she is pregnant, Joe is wearing suspenders over his shoulders. As the camera moves back and forth between the characters during the dialogue, Joe's suspenders "disappear." When the camera pans out, you can see that they are now hanging below his waist.
Factual error: Danny Greene has a bomb placed in Shondor Birns' car. As Birns is waiting to cross the sidewalk, the pedestrian walk-don't walk sign is a modern digital sign, that was not around in 1975.
Plot hole: When Sam first encounters Dan, the headmaster, Dan reveals that he had to quit his musical career when he impregnated and married a groupie, but that he loved his daughter. Later, Sam runs into Courtney behind a liquor store, and Courtney, who is actually Dan's above-mentioned daughter, discusses her "aggro older brother". If Dan's original error in timing resulted in a daughter, how could she have an older brother?
Revealing mistake: When Umi is first descending the stairs in her house, her left hand clips through the left railing.
Continuity mistake: Late in the movie, when Anya says goodbye to Patrick, she takes off her wedding ring and puts it on the table before leaving the café. In the next scene, her wedding ring is visible on her hand throughout her call from the phone booth.
Continuity mistake: When Laurence asks Colin for a cigarette in the screening room, he has it between his fingers when Colin lights it, but when the shot cuts, his fingers have disappeared from around the cigarette. (00:45:30)
Other mistake: At the beginning, the arrival board has the cities listed in alphabetical order, but "San Francisco" comes after "San Jose" when it should come before it.
