Ricky surprises Rupert Grint

This weekend open auditions will be held to find a girl to star in JK Rowling's Harry Potter spin-off film.

Back in 2011 Ricky surprised Rupert Grint, with a clip of his first ever interview with Newsround.

Rupert hadn't done any professional acting before he won the role of Ron Weasley.

He first heard about the original open auditions whilst watching Newsround!

Take a look at Rupert's reaction...
