" James Corden has revealed that he will not be singing in the upcoming film One Chance. The Gavin &amp;amp;amp; Stacey actor portrays original Britain&amp;#039;s Got Talent winner and opera singer Paul Potts in the biopic.  However, Potts&amp;#039;s own vocals will be used to dub over Corden&amp;#039;s lip-synching in the film, he confirmed to The AP. Speaking at the Toronto Film Festival, Corden explained: &amp;quot;It was very, very straightforward. I would pretend to be singing opera, and then Paul would go into the studio and loop to my mouth. &amp;quot;I hope I haven&amp;#039;t given it away too much, but that&amp;#039;s basically what happened.&amp;quot; Taylor Swift has also revealed that she has written a song for the movie for Corden&amp;#039;s co-star Alexandra Roach to perform in the film.   She said of the film: &amp;quot;It&amp;#039;s amazing to be a part of this project. It&amp;#039;s a movie that really moved me in a way that I haven&amp;#039;t been moved in a long time, and to have just a small part in telling the story. &amp;quot;I wrote the end credits song so it&amp;#039;s the last thing you see of the story and I&amp;#039;m really, really honoured.&amp;quot; Roach said of watching Paul Potts back in 2007: &amp;quot;I was in hospital at the time and I remember me and three old ladies gathered around the communal television in our ward, and we watched him sing. &amp;quot;And because he was from Swansea and I was in a South Wales hospital then we were all crying and weeping and really rooting for him. And it&amp;#039;s so bizarre now to think that I&amp;#039;m sharing a red carpet with him and I&amp;#039;m playing his wife! It&amp;#039;s mad!&amp;quot;      Julie Walters and Colm Meaney co-star in the film as the parents of the singer from Bristol who shot to stardom thanks to the television talent contest. Devil Wears Prada director David Frankel&amp;#039;s film also stars Mackenzie Crook and Jemima Rooper with cameos from Simon Cowell and Amanda Holden. One Chance will open at cinemas on October 25.
