Factual error: Pettis' calculation of the amount Connor needed to replace his asset was way off. He stated, "[Cornell] brought me about 250 [$250,000] a year. He had at least 20 more years of service. Subtract five years he might have spent in prison, so you owe me, what? Six point two million." Pettis was presented as intelligent, but a quick mental calculation of even the full 20 years at $250,000 would total only $5 million (not $6.2 - an odd sum). For 15 years, the total would be $3,750,000. (00:28:45)
Continuity mistake: When The Artist is talking on the phone to Detective Mary Kelly, sometimes his long, wavy hair behind the phone is flat and other times fluffy (extending wider than the phone). (00:14:45)
Factual error: At the end of the film a character is walking through a studio lot in 1952. Through the trees behind him can be seen a section of a poster advertising Jackass Forever (2022).
Revealing mistake: There's something odd about the chair that is (or is not?) to the right of Monsignor Kelly when Stu goes into his office to talk. Only part of the back of the chair can be seen and it is not directly in front of the Monsignor, but there is not enough room for the seat part to be there (otherwise, the Monsignor could not be standing where he is). Without any indication that the Monsignor or chair moved, the Monsignor is later able to rest his right hand on the chair's back. (01:13:57 - 01:14:37)
Continuity mistake: After Art yells for Jesse to come to eat lunch, the stick of butter on the plate is roughly parallel to the edge of the table, but is diagonal when Art and Jess come to the table. A later view from the other end of the table shows the stick of butter parallel to the edge again. Some of the family members take a roll out of the basket, but none take any butter (so did not move it). (00:20:45)
Continuity mistake: Banker Mr. Anderson picks up his glasses from the desk and holds them near his face, then picks them up a second time. (00:51:35)
Revealing mistake: Driving home from meeting Gigi, there is an image on the windshield of a blue handicapped parking permit/placard that is supposed to be hung on the rearview mirror, but there is no placard hanging - the permit's image is superimposed on the windshield. The image even briefly appears and reappears. (00:34:05)
Continuity mistake: Solomon put the rope around his waist underneath his coat, but when he was walking through the woods the rope was tied over his coat. Also, the knot would start out in the front of his left side but change to behind his back even though the rope was loose (not taut) behind him. (00:01:55 - 00:02:26)
