Continuity mistake: There's an electrical outlet on the wall below the window (aligned with the window shade's loop) in Sid's room near the Megadork poster, but when Sid throws Woody to the floor and raises the shade (before he scorches Woody's forehead with the magnifying glass), that outlet has vanished.
Visible crew/equipment: After Josh tells Cher she's such a brat, at the start of the next shot which is the first close-up of Cher during the driver's test, just as she says, "I had an overwhelming sense of ickiness, even though I apologized to Lucy," the top of a crewmember's head, with his short wavy hair blowing in the wind, is reflected at the bottom of the Jeep's windshield, directly in front of Cher and the steering wheel.

Continuity mistake: When the two female characters enter the fancy hotel room, they make a point to say they will only be there for a couple of minutes. It is daylight when they go in. The visit is cut short (the one that's supposed to be a few minutes long) because of a gun battle in which one of the women dies and the other escapes. The escaped one gets out through the roof into an evening's sky. There's still light visible, but for a visit that lasts all of 4 minutes, it's far too quick a change. (00:23:00)

Plot hole: When Charlie sets out to hijack the money train, he jumps off the platform onto the tracks as it arrives, in plain sight of the driver and other passengers at the station, and only puts his mask on once he's in position on the tracks. The train conveniently stops right over top of Charlie, allowing him to enter through the conveniently-placed grate on the train's floor. (01:17:15)
