Factual error: Billy Bob Thorton wore a uniform with a Louisiana state patch on it. All of the cars have Georgia license plates.
Continuity mistake: When Alita is playing the street version of motor ball she knocks over Tanji. In the next shot Tanji is following her in the pack as she scores, then the shot switches back to him on the ground.
Plot hole: The Bishop in the film is performing the duties you would expect of someone in his position (giving mass, hearing confessions, performing weddings etc.) He has his own private chambers in the cathedral, refers to Robin as 'the boy I knew' and talks about hearing his Father's confession four months earlier; so he's been around for a while. The problem is the credits refer to him as the 'Bishop of Hereford'. No explanation is ever given for why the Bishop of a city 100 miles away is living and working in Nottingham rather than looking after his own diocese; or why the Bishop of Nottingham isn't around to look after his. (The Bishop of Hereford was an enemy of Robin Hood in the original ballads, and it's likely the filmmakers just gave that name to the Bishop in the film due to its familiarity, without thinking about the plot hole this creates).
Continuity mistake: Near the end of the movie, when Parker and Hunt are on the bus going to the contest, you'll see that Parker's hair is in waves. But when she arrives at the studio, her hair is VERY curly. Its not likely that she had time to change her hairstyle THAT drastically if she was pressed for time as she very clearly was.
Revealing mistake: When you see the first shot of the dead Mercutio, he's still breathing.
Continuity mistake: When Lolita begins to undress in front of Humbert, she is wearing her school uniform. Her shirt first appears tucked in, then out and then in again.
Continuity mistake: Hester's estrange husband mistakenly kills a man at the end, and you see him cut his hair and his scalp off, then later when people find his body (after his suicide) his hair and scalp are intact. Then later you see him with the hair and scalp in his hands again.
Factual error: The film is set in 1997. There is a scene where Amelie knocks on a house door and in the background is a new model VW Beetle. These weren't available until early 1998. You can also see several scenes with various new models of Fiat Punto and VW Golf which weren't available until 1999. (00:19:00)
Continuity mistake: On the jousting scene where William loses his helmet, he has a monstrous bruise under his right eye (in the late afternoon). That night at the banquet, there is no trace of the bruise. So far as I know, even a black eye doesn't completely heal that quickly. (00:49:50 - 00:55:25)
Revealing mistake: A horse gallops through a field and you can see a telephone pole.
Factual error: When Forrest and Lt. Dan first try catching shrimp on the new boat in the mid 70s, they catch a bunch of junk, including a Mello Yello can, which wasn't launched until 1979. (01:30:05)
Continuity mistake: Indians are on a hilltop and a jet vapour trail can be seen in the sky.
Continuity mistake: After Mike and Ned fight with lightsabers, when they are in the kitchen Mike's wedding ring moves from his left hand to his right hand and back again, depending on the angle of the shot. (00:21:05)
Continuity mistake: Apollonia jumps into the lake. She is soaking wet, naturally. However, soon after, she's riding on the back of Prince's motorcycle and her hair is completely dry. (00:23:34)
Continuity mistake: In one of the ice skating rink scenes, the camera looks at John Cusack and there is no snow falling. It then cuts to Kate Beckinsale and it is snowing heavily. (00:09:25)
Continuity mistake: When everybody is at the rehearsal for Grant and Julia's wedding, when Bernie does a toast to Julia and Grant, watch the level of water in Roz's glass, it changes without her even touching it.
Continuity mistake: When the family is getting into the car to go to the wedding one grandmother says to the other "let me in". The grandmother gets out to let the other grandmother in but the first grandmother never gets back in the car, she just pretends to. You can see her hiding behind the cars as it backs down the drive. Both grandmothers are in the car when they see Long Duk Dong on the lawn.
Continuity mistake: Look at the dirt when Herbie backs away from the nose of the newer Beetle, between the races out in the desert. Although Herbie drove straight up to the newer Beetle, tire marks can be seen where the crew moved the car back and forth to get him lined up.
Continuity mistake: When Napoleon is waiting while Rico makes a sale, he checks his watch to see how much time he has before the dance. The first time he checks it, the date on the watch indicates Thursday July 17. When he checks it again a few minutes later, it shows Monday July 21.
Continuity mistake: When Andy and Trish argue in the bedroom, the bed is covered in action figure boxes. Between shots just as Andy leaves, a 'Dracula' action figure box disappears. (01:43:10)
