Although there's no word from Warner Bros, who made the film, DVDAnswers claims there will be deleted scenes not included in the cinema release.

The site also says there'll be special games, documentaries and an interview with author JK Rowling herself!

There's no news on the UK release date, but it should hit the US in November.

Among the games are a chance to help Crookshanks catch Scabbers and an unexpected quest with Sir Cadogan.

The cast are interviewed by Johnny Vaughan and the Shrunken Head from the Knight Bus.

The site also says there will be interactive tours of Honeyduke's sweetshop and Professor Lupin's classroom.
