First game to feature free-roaming any area with a non-fixed path and adjustable camera since "Prisoner of Azkaban"
The last Harry Potter title to be released on the PlayStation 2 & the PlayStation Portable.
This is the third Harry Potter game in a row to feature cast members from the film providing the voices of their characters.
There was cutscene after Harry made a Shriking Solution stating that he was asking Ginny to go to Hogsmeade which she denied. During that, you can hear a record screening sound effect, making this one of the hilarious backdrops in an HP game.
