Warner Bros. Studio Tour London - The Making of Harry Potter has opened its doors to Muggles this week, giving the public - for the first time in Harry Potter's 10 year film history - a chance to snoop around the actual set where the on-screen magic was made.

On the tour, we caught up with stars of the film Tom Felton - who played Draco Malfoy, Warwick Davis - whose roles included goblin sGriphook and Hogwarts Professor Filius Flitwick, as well as the charming Evanna Lynch, best known as Luna Lovegood, and Natalia Tena who played Nymphadora Tonks, to find out how it feels to be back at Hogwarts and what they miss most about playing their characters.

We also spoke to Oscar-winning special effects supervisor John Richardson who worked on all of the Harry Potter films and was responsible for bringing Qudditch to life. Plus Nick Dudman, the special make-up effects boss who worked on the magical animatronic creatures, including Hagrid's bird-like creature Buckbeak. Find out their biggest Potter challenge in the video above.
