Continuity mistake: Whilst Walt and Bob are cooking at the beginning of the film, there is a large bandage on Bob's forehead. Just after chopping up the mushrooms the bandage disappears, the next time we see them it is back on. (00:03:05)
Continuity mistake: When the boys are first laying out the buns the second bun from the left in the front row has a yellow stain on it. When it comes back to them about to put ketchup and mustard on the buns the stain is missing. (00:03:25)
Continuity mistake: At the beginning the ketchup and mustard dollops put on the buns originally are not the same as when they start flipping burgers onto the buns a bit later. (00:03:50)
Continuity mistake: When Bob and Walt walk by the harbour it is snowing heavily, then in the next shot it almost seems to have stopped snowing. (00:12:50)
Continuity mistake: When Walt is telling Bob that he wants to be an actor, the tassel on Bob's hat changes from angling back to looping forward. (00:15:55)
Continuity mistake: When they are getting on the bus after being turned down by some agents there is a guy with a red shirt getting on the bus. The scene cuts and shows the guy with the red shirt smoking but not on the bus. The other people in the shots are mixed up, too (the only one that stays the same is the girl Walt hits on). (00:25:15)
Continuity mistake: When Bob and Walt are having lunch you can spot a bottle of Tabasco on the counter beside them. In the next shot the Tabasco is gone. Then it appears again. (01:13:50)
Continuity mistake: When they're talking about the operation in the diner, the coffee mug in front of Walt is pointing to the left of the screen. In a later shot it is pointing almost directly toward the camera. (01:16:05)
Continuity mistake: In the diner, when the camera shoots the twins from the other side of the table, a sugar bottle can be seen. However, when it shoots from Bob's side of the table a bottle of hot sauce can be seen (it should be seen from the other angle as well, but is absent). (01:16:50)
Continuity mistake: In the shot where Bob and Walt are in jail and Walt is eating, you can see a cop holding a cup of coffee with both hands. In the next shot he is holding it with only one hand. (01:17:05)
Continuity mistake: When May comes back to talk to Bob, the torch behind her is not lit. When it cuts to a different angle the torch is lit. (01:23:20)
Continuity mistake: When Bob takes May to talk in private, after she returns, April is holding a bottle of beer. When the scene cuts to them walking down the pool, April can be seen in the background with no bottle. (01:23:40)
Continuity mistake: While May and Bob are talking in private, there is a clump of leaves in the pool that appears near the life jacket, which wasn't there in an earlier scene. (01:24:05 - 01:25:55)
Continuity mistake: When May is talking to Bob in private her hair goes from being over both shoulders to being over one, to being over both, etc. (01:24:15)
Continuity mistake: At the end when Bob walks out to see who played the song, there is an order pad sitting near the end of the counter. When Bob walks out with Walt the pad has turned into what looks like a menu and moved to the very corner. (01:42:55)
Continuity mistake: In the scene where Moe shows the Tenor brothers their apartment, the star on the door is gold. Later when Morty is riding around on the scooter, you can see the star on their door has changed to silver. It changes many more times throughout the movie.
Continuity mistake: Right before Bob has his first panic attack, Walt is holding the newspaper in his left hand. When the shots change, it ends up in his right hand without him moving it.
Continuity mistake: When Bob has his first panic attack (about Walt's one-man play), he takes a glove off to hold the paper bag, but a few shots after he's wearing both gloves, without putting the glove back on.
Continuity mistake: When Morty first appears, almost all his below teeth are gone, however throughout the movie this keeps changing, from having all from having one to none.
Continuity mistake: We see that the join between Bob and Walt is very flexible, and can be twisted and contorted easily. Why is it then that when the brothers are lying in bed and Bob turns on his side to sleep, does Walt move with him. They should in fact be facing away from each other.
Chosen answer: Greg Kinnear is singing himself - DVD commentary.
