Help finding film

OK my friend is on MSN and is freaking out because she watched a film the other day and can't remember what it's called.

The only info I have is that there are magic talking books which a young boy gets transported into and then he finds himself in an animated world, he slays a dragon, finds a wizard and then goes back to "real life" and the wizard is a librarian, he then goes home to a tree house and the books come alive again.

She *thinks* an actor from Little Vampire was in it.
