Always thought you had the right stuff to be a Harry Potter film star? Now's your chance.
Thanks to Microsoft and Warner Brothers, fans will have the chance to get their Gryffindor on and hang out with Emma Watson, Daniel Radcliffe, and crew:
Fans will have to complete an online quiz on Harry Potter and the Order of the Phoenix as part of the competition, arranged by Warner Home Video and Microsoft Digital Advertising Solutions' UK division.
Those who answer all the questions correctly will get the chance to appear in the next film, Harry Potter and the Half-Blood Prince.
The real question is which part Microsoft will be playing...Lord Voldemort, anyone? ;-)
