Other mistake: When Arthur takes Harry aside at the Leaky Cauldron, the moment before Arthur says, "There are some within the Ministry who would strongly discourage me from divulging what I'm about to reveal..." we can see the digital number "300" flash on the stone pillar to the right of the wanted poster. (This occurs only in the fullscreen version, as opposed to a widescreen version where the number "301" flashes underneath the poster, which is noted in another mistake). (00:17:30)






Chosen answer: Fred and George used the map to aid them in their mischievous activities at Hogwarts, and probably had little interest in what their little brother was doing or who he might be with at any given time.
