Just thought I would post these there interesting... and I was wondering did you notcie them?
Revealing mistakes: In opening scene in Harry's bedroom, it can be seen in one shot that Harry is lying on a sheet of glass (to allow magical lighting effect) rather than on a sheet.
Continuity: When Dudley is watching television, he is watching "Generation Game, The" (1971). We see a contestant put some headphones on, and in the next shot we see the same clip.
Continuity: At the end of the scene where the class have been dealing with the Boggart, the shot has been flipped and Harry's scar switches sides.
I noticed the Scar one only because Tonks07 asked me to watch out for it because he thought he saw it... so i did and long and behold it was...

didn't notice the two other ones though... :/ I'll have to go watch the movie again...
