The Hurt Locker – Xbox Games
In the movie, you can see the characters playing a game on Xbox 360. The Xbox itself didn’t come out until 2005, and the game they were playing, Gears of War, was released in 2006.
As the movie took place in 2004, this little error is enough to make it on our list.
Harry Potter And The Chamber of Secrets – Cameraman On Set
You can find tons of bloopers of the famous Harry Potter film series. It is probably because most of the actors in the films were kids. But there is one particular blooper that is absurd and unbelievable.
You may remember the scene in which Malfoy is on the ground, and Hogwarts students are looking at him. In that scene, you can clearly see a cameraman, and it makes one think that the editors were smoking something during post-production.
