Rupert Grint wishes he could wear an "invisibility cloak" at music festivals. The 'Harry Potter' actor has joked he would like to use some of the magic accessories from the wizard series to allow him to walk around without being recognised and mobbed in public. He admitted: "I've sometimes has a bit of trouble at music festivals. It's usually fine, but if you're in a massive crowd of drunken people and one of them suddenly spots you, it gets hard to move around. "Sometimes you want a bit of invisibility. Perhaps I should wear an invisibility cloak - that would be handy! But I have actually experimented with disguises. "Once I wore a horse's head disguise for an entire festival. It wasn't comfortable, and I got quite claustrophobic, but it really worked. It was quite liberating. I felt completely free!" He added: "'Bloody hell, Harry!' is something people say a lot! The attention has never bothered me too much. It's part of it and I'm used to it. It's quite manageable. "It's just friendly people coming up to you. It's not anything crazy. And those people are the ones buying cinema tickets. If it wasn't for them, I wouldn't be where I am today."
