This latest Lego Harry Potter trailer finds the boy wizard in his third year at Hogwarts. Apparently it's Time to get Sirius. Can you see what they've done there?
Anyway, this action is all taken from the Prisoner Of Azkaban section of the game meaning Harry will be doing battle with Dementors using his Petronus. We'll leave the knob gags to you guys on that one.
