Harry Potter and the Half-Blood Prince released in U.S. theatres less than two weeks ago on 15 July (09) but has already notched up a whopping 57 mistakes. Each mistake has been detailed on website MovieMistakes.com, reports the Daily Express.
In one scene of the sixth instalment of the wizard franchise, Rupert Grint's character Ron Weasley can be heard speaking but his mouth doesn't move. In another scene, Daniel Radcliffe's character Harry Potter appears with a windswept and messy hairstyle just seconds after his locks were neatly combed.
The number of mistakes means Harry Potter is leading a list of the year's most mistake-ridden films. It has beaten Transformers: Revenge of the Fallen, which was littered with 53 bloopers.
