The waiting is over... the first poster featuring James Corden as 'Britain's Got Talent' winner Paul Potts has arrived.

We got out first look at the 'Gavin & Stacey' star playing Potts earlier in the summer, opposite Mackenzie Crook in a branch of Carphone Warehouse, where Potts worked before scooping the BGT prize in 2007.

Now we have the first poster for 'One Chance', the biopic produced by the Weinstein Company and directed by David Frankel, who helmed 'Marley & Me' and 'The Devil Wears Prada'.

There's also a new still, featuring Potts about to audition for 'Britain's Got Talent'.

Joining Corden on the bill are Julie Walters, Colm Meaney, Jemima Rooper and Alexandra Roach, who plays Potts' wife Julie-Ann.

Potts has revealed that he was offered a cameo in the film, sitting in a pew at his own wedding, but turned it down as he didn't want to put Corden off.

It's due for release in the UK on October 25.
