One Chance tells the story of Potts as he dreams of leaving the Welsh industrial steel town he grew up in to become a successful opera singer.
And while Corden believes the film will be a huge success, he admitted to This Morning's Phillip and Holly that he was not immediately convinced that the public would be interested in the story.
He said: "I had the same feeling I think everybody has when they hear that they want to make this (story) into a film, which was "really?".
"And then I went and met the director, who has made films like The Devil Wears Prada and Marley and Me and I said "why do you want to make this film?".
"He said that the two-minute YouTube clip that we have all watched of Paul singing (on Britain's Got Talent) is hugely emotional as a two-minute clip and imagine if you knew everything that had gone on before in his life and how much it meant to get on the stage that day.
"And that's kind of the best thing about the film, is that it stops at that moment."
Paul Potts came to prominence in 2007 when auditioned for Britain's Got Talent and was eventually crowned the winner of the first series.
Since then, Potts has gone on to forge a hugely successful career as an opera singer.
Corden explained how the film had tones of Billy Elliott and Rocky within the script and it was an uplifting story that people would not expect.
"My first vision of the movie would be that there would be an actor playing Simon Cowell and there is none of that," he said.
"I didn't really know anything (about his life) and then suddenly after reading the script I realised how many hurdles he had to jump to get to that point and how he just persevered through such adversity.
"The truth is the film is a love story really about Paul and his now wife. He meets this woman who is the first person to ever believe in him."
