Revealing mistakes: At the end of the movie, during the press conference, Anna is seen in the window in the background, and when the camera closes in on her, two panes of glass are clearly missing from the part of the window Anna is standing behind.
Revealing mistakes: In the bungee jump scene, the slow motion shot is obviously two dummies.
Continuity: In the hotel scene where Anna's mother and father are discussing Anna's "freedom", the right side of Anna's mother's robe is all the way across her chest. In the next shot it is half way across her chest and the next shot it is not across her chest at all, yet she doesn't move the entire time.
Errors made by characters (possibly deliberate errors by the filmmakers): When the President, his wife and daughter are playing scrabble. The daughter places down Zygote and claims 40 points. A clear shot of the board shows that she should actually claim 60 points Z=10, Y=4, G=2, O=1, T=2 (1+double letter score) and E=1 each: total 20 x triple word = 60
Continuity: When Anna is being taken away from the Love Parade by helicopter, Ben watches on. His shirt is seen being blown flat against him, then lifted revealing his abdomen, then flat again.
Errors in geography: When the news report at the beginning of the film shows Anna being toured around Prague, there is a segment showing Anna having a "photo op" at Prague Castle. In the shot, Prague Castle is clearly visible in the far distance in the background of the shot.
Continuity: After Anna wipes the s'mores on Ben's face, she slowly tries to wipe it off in a flirty manner. But when the camera turns back at Ben after she wipes it off, his face looks clean, as if nothing ever touched it. Plus, Anna's hand is now clean, too.
Audio/visual unsynchronized: When Anna is approaching the bridge where the bungee jumpers are, the sound of her footsteps doesn't match the shoes she's wearing.
Factual errors: The G8 summit takes place in Prague - the capitol of the Czech Republic. However, the Czech Republic isn't part of the G8 and the G8 summit only takes place in countries, that are members of the G8.
Factual errors: When McGruff gets a tattoo it is ready instantly, anyone who ever had a tattoo can testify that it can take up to two weeks to heal and you DON'T want to walk around in the sunshine with it during that time.
Continuity: Anna and Ben have supposedly been completely robbed by McGruff, but Ben has money to buy the little boys bike when he is chasing after Anna.
