Pictures: Harry Potter Studio Tour, Leavesden StudiosPublished30 March 2012Image caption, Ever dreamed of taking a stroll down Diagon Alley? Well, very soon you could be doing just that...Image caption, See Hogwarts itself in all its glory. Well - it's a model of course, but it's still pretty cool. It's part of a new exhibition: the Harry Potter Studio Tour at Warner Brothers Leavesden Studios, near Watford.Image caption, The tour lets you get up close and personal with loads of the weird and wonderful props and buildings featured in the wizarding series, like these potion jars.Image caption, Just because they're models doesn't mean they're not scary! Check out Aragog the spider - creepy!Image caption, Check out this close-up of an amazing mermaid prop. It's got loads of detail like the teeth and the ears.Image caption, You can stand in the Great Hall and imagine you're in Gryffindor banqueting with Harry and Hermione...Image caption, Or, like these fans, you can take a magic spin in the Weasley's little blue car.Image caption, Maybe you'd like to climb aboard the purple triple-decker Knight Bus from Harry Potter and the Prisoner of Azkaban.Image caption, The entrance to the Great Hall might look really old - but it's just another newly-built set like the rest of it!Image caption, In Dumbledore's office you can check out all his wizard portraits - unfortunately there wasn't enough room for his phoenix, it was a bit of a fire hazard...Image caption, Up close, all of the goblin masks from the workers at Gringotts Wizarding Bank look pretty scary! The studios open to muggles on Saturday 31 March - but tickets are sold out for weeks.
