Robbie Coltrane tells Jonathan Ross this Friday that it’s time for Cracker – The Movie.

Appearing on this week’s Friday Night With Jonathan Ross, the Harry Potter star says he’d love to see his acclaimed crime-cracking psychologist character on the big screen.

Robbie tells Jonathan: “We always wanted to do a film. All you have to do to raise the money is say that George Clooney is a possible suspect.”

Also on the show is British tennis no.1 Andy Murray, who tells Jonathan that he can win Wimbledon.

He says: “Yes, why not? You have to think you’ve got a chance of winning.”

Andy says he thinks the lack of star British players in tennis is a class issue.

He says: “I think that’s a problem. It was difficult for me to get courts in Scotland, it was easier to play football. I moved to Spain because I thought it was more competitive.”

And he tells Jonathan that the best women players are Russian.

“The Russians are pretty special,” he says.
