Continuity mistake: When Robert Crumb is looking at Harvey Pekar's drawings for comic-book ideas while the two eat in a restaurant, the level of the drink in Harvey's glass switches between full and two-thirds full several times.
Continuity mistake: Dwight is showing Toby a Boy's Life magazine. As the camera angle changes he goes from holding it with the back of his hand facing Toby to facing away and back again. (00:45:50)
Factual error: When the audience are watching the pilot, Davy says "It's Russell!" But in the actual pilot, it's Micky who says it.
Continuity mistake: Early in the film, Michael talks to Harry Boland on a boat. During this scene, a cigarette appears in Boland's mouth that was not in the previous shot. (00:40:40)
Factual error: The movie is set in Rwanda in 1994. At the start of the movie you see a billboard advert for MTN, a South African cellular service provider that was not available in Rwanda in 1994.
Continuity mistake: Just before Burt gets ready for his record-setting attempt, he wraps some asbestos cloth around his leg to protect it from the hot exhaust pipe. This does not allow him to fit his leg within the cowling of the bike, so he throws it off and puts his leg in without the protective covering. As he inserts his leg into the cowling, you can see that his pants leg is bunched up around his calf, not tucked into the top of his sock, as is Burt's usual procedure. However, a close up of the leg only a few moments later shows the pants leg tucked into the sock, and he could never have done that once he was fully seated in the cowling.
Factual error: Chuck and Penny are seen drinking Rolling Rock beer in clear glass bottles. But Rolling Rock beer has always come in green glass bottles.
Factual error: Buster Franklin's bass player is playing a MusicMan StingRay bass, even though they didn't appear on the market until 1976. The guitar isn't from the fifties either, but I can't make out what it is. (02:12:30 - 02:14:50)
Visible crew/equipment: Peter comes home after having sex with the Sophia Loren stand-in, and when he walks into the lounge room and finds Michael and the babysitter asleep on the couch, a camera shadow is visible on the lamp shade.
Continuity mistake: In the scene where they ride to the top of a hill on horseback, you can see a white van and power lines in the distance.
Continuity mistake: Has a scene set during the Festival of Britain (1951). Oldman and Molina are shown at night on the South Bank of the Thames, ostensibly having just attended the Festival. In the background is a very clear view of New Zealand House, which wasn't built until the early 1960s, some ten years after the scene was supposed to take place.
Factual error: Philip uses his left hand to sign the decree declaring Joan officially crazy. No one in the 15th century would have used his left hand to write, as 1) it was considered the wrong hand to write with and 2) writing with the left hand would have smudged the fresh ink and rendered any document unreadable.
Continuity mistake: When Roberta is in Brian's apartment, she is putting curlers in her hair and then Brian walks in and they start talking. Roberta then stands up and Brian kisses her neck and as she turns around you can see the curlers have disappeared.
Visible crew/equipment: When Sylvia and Barrie go inside the house after the children's fight, the camera crew is reflected on the window.
Factual error: The issue of "Guideposts" shown by Crane's interviewers is from the early '90s.
Continuity mistake: When Basquiat is painting on a sign with a horse on it, he puts a white line through the horse. When Warhol has a look at it, the stripe no longer covers the horse.
Continuity mistake: Near the beginning of the film, "Elvis" is driving Byron's car, and has a diamond horseshoe ring on. They show a close up of it as he's driving, and in a subsequent scene, the ring has been turned around.
Other mistake: In the scene in which two Japanese Zero fighters bomb and strafe a PT base, shots of the attacking planes show them carrying no bombs. During the attack, they still drop around 20 bombs anyway, which is considerably more than the actual carrying capacity of the two planes.
Other mistake: One of the shots of the aftermath of the battle is played in reverse - e.g. the smoke from the fires is going down. (01:41:20)
Factual error: After they finally start spending money, and after you see them in the older model black Mercedes Benz S-Class, you see clearly a newer model silver Chevrolet Corvette ('05-'09), even though the scene is supposed to be taking place during the latter part of 1996 or early 1997.
