Well, we have to say we are pleasantly surprised by the actors landed for the Paul Potts movie biopic.
The project, which will start shooting in October, tells the story of the very first Britain's Got Talent winner's rise from rags to riches.
And the man enlisted for the job is none other than award-winning star of stage and screen James Corden.

Joining him will be Julie Walters as his mother and Mackenzie Crook as his best friend.
Alexandra Roach from The Iron Lady has been tapped to play his wift Julie-Ann Cooper, a role previously thought to be assigned to Katy Perry.
Speaking to Digital Spy, director David Frankel said: "We start shooting in about six or seven weeks. It'll be done by Christmas.
"It's just the Rocky story. I think most people were not aware of the full extent of the adversity that [Potts suffered], but it's also a love story.
"It's a story of this guy who meets a woman online, a guy with no confidence, still living at home with his parents and working in a Carphone Warehouse, and he meets this woman who just believes in him. Almost for no reason. Because she loves him, she believes in him, and she won't let him give up his dream."
Simon Cowell is rumoured to be playing himself in the film.
