Easter egg: 2nd disc: Go into the Great Hall and choose "The Quest of Sir Cadogan". During the introduction to the challenge, between the part when you see Sir Cadogan sleeping (maybe) and when he gives flowers to a girl, hit the left arrow on your remote and you'll automatically go to the picture gallery (which you will also get to if you play the challenge and get the highest rank). You'll still have to play the challenge afterwards, though, unless if you hit Menu.
Harry Potter and the Prisoner of Azkaban (2004)
1 easter egg
Directed by: Alfonso Cuaron
Starring: Gary Oldman, Maggie Smith, Alan Rickman, Michael Gambon, David Thewlis, Daniel Radcliffe, Emma Watson, Robbie Coltrane, Tom Felton, Rupert Grint, Richard Griffiths, Robert Hardy
Genres: Adventure, Family, Fantasy, Harry Potter
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)
Sirius Black: Brilliant, Snape. Once again you've put your keen and penetrating mind to the task and as usual come to the wrong conclusion.

Chosen answer: It's not known what it is. It is left to the audience's imagination of what exactly is in the room or what some witch or wizard was doing in there. This is only meant to be a humorous bit and is unrelated to the plot. It didn't happen in the book.
