We announced earlier today that Matthew Lewis was a contestant on the BBC's Celebrity Mastermind, which was aired at 7:00pm GMT this evening. The video is available now for all to view (the entire segment can be seen by UK viewers on the BBC iPlayer), where Matt answers quite a lot of questions about rock band Oasis, as well as general knowledge trivia. Matt is also asked about Harry Potter, and notes Neville's weight loss and resistance group set up in Deathly Hallows.

Thanks to Tom Duncan for the video!
