Flippin' heck, Harry, isn't that Ian Brown?

Yes, there he is sitting in the Leaky Cauldron, his tea magically stirring while he reads "A Brief History of Time". The former Stone Roses frontman himself, in a rather unexpected cameo in the fab new Harry Potter film. Wonder who we should watch out for in the next instalment - Shaun Ryder? Liam Gallagher? Robbie bloody Williams?
