Upcoming mobile game Harry Potter: Hogwarts Mystery has roped in a line-up of voice talent from the Harry Potter movie series - including Dame Maggie Smith back as Professor McGonagall and Michael Gambon returning as Professor Dumbledore.
Hogwarts Mystery will launch for iPhone, iPad and Android devices worldwide on 25th April and let you attend Hogwarts as a student.
The game is set a few years before Harry attended the wizarding school himself - but you'll still get to take lessons with familiar teachers and hang out with the younger versions of other characters, like Bill and Tonks.
As well as Smith and Gambon, Hogwarts Mystery will also feature Warwick Davis as Professor Flitwick, plus the original Madam Pomfrey, Hooch and Pince - AKA Gemma Jones, Zoe Wanamaker and Sally Mortemore.
The return of these actors is a coup - it's not something many Harry Potter tie-ins can boast. How will the game play, though? We don't have long to find out.
