Ron Weasley, noooo! 'Harry Potter' actors get sorted into Hogwarts houses - CNET

Of course, Harry, Hermione and Ron are natural Gryffindors through and through. Right? Well, there was that stuttery moment when the Sorting Hat suggested Harry might do well in Slytherin, but honestly it's tough to imagine the three Harry Potter heroes wearing anything but the red and gold.

Not quite the case, though, for the actors in the movie. Author J.K. Rowling's site, Pottermore, features an online quiz that sorts users into the four Hogwarts houses, and some of the movie's stars had surprising results.

Rupert Grint, who played Ron Weasley in the films, had the confidence of a bo Gryffindor going into his test. "Well, it'd have to be Gryffindor, I think," he said. "That's what I feel, I belong there."

So much for intuition. Grint was sorted into the loyal, patient and hardworking house of Hufflepuff, and like a true Hufflepuff badger, made the best of it. "I feel pretty good," he announced. "It wasn't what I was expecting."

Matthew Lewis, who played Gryffindor Neville Longbottom in the films, also joined Grint in switching to Hufflepuff -- and revealed during the sorting process that he'd never snitch on a cheating friend.
