Continuity mistake: In the chase scene the American Mini swerves to miss an oncoming car. That car starts out grey then changes to a another green Mini, then back to the original car that came round the corner.
Continuity mistake: Lars jumps into the summer water while wearing yellow pants, comes out wearing red, and is back in yellow pants on the flight back to Scotland.
Continuity mistake: Olaf drives away after chewing off the parking ticket. Lars sighs and concurs that his dad IS in fact ashamed of him. He has his hands in his pants, but when in the next shot Sigrit tells him it's not true, his hands are in the upper pockets of his jacket. (00:08:30)
Continuity mistake: When Will Ferrell and Pierce Brosnan have their conversation about the house in front of the tomb, the natural light changes very between shots (when Brosnan says "I make my money fishing" Ferrell's shoulder and face are fully lit by direct sunlight, gone at the next cut). (00:06:30)
Continuity mistake: During Abba's performance, the toy young Lars is playing with changes position between shots. Specifically, when the song says "At Waterloo Napoleon did surrender", the wooden tile laid flat on the step is pointed towards the camera, and after the cut it moved 90°. (00:01:35)
Continuity mistake: Abba is about to perform "Waterloo" and one of the women hushes the others spreading her arms. Most beer bottles in that particular shot have gotten their cap back on. (00:01:20)
Continuity mistake: When the flaming severed arm falls in front of Lars and Sigrit, its position is different between shots; it fell across the horizontal lines of the railing's shadow, but in close-up it's parallel to them, and when they kick it, it rolls over obviously different spots (easy to tell by the width of the shadow). (00:26:45)
Continuity mistake: During the exhibition of "21st Century Viking", one of the bar patrons calls the attention of the others; his hand changes position on the glass between shots, the guy with a shaved head and short black beard is holding his beer with his right hand instead of both, etc. (00:21:45)
Continuity mistake: Neils Brongus puts next to him in the conference room the DVD with Demi Lovato's performance. The DVD is placed in the first shot on top of the remote control, but already in the next shot it's off it, and it keeps bouncing between these two positions and different ones depending from the camera angles. (00:13:20)
