Before the dramatic emergence of Susan Boyle, there was a man called Paul Potts.
Like Boyle, he came from a simple background and always dreamed of singing.
One Chance is based on his story, and what a wonderful story it is. Potts (played by the talented James Corden) grew up in the Welsh town of Port Talbot, where a job at the steel mill was about the best you could aspire to do.
Bullied throughout his childhood, Potts never gave in and wouldn't be quietened from his singing - the only real joy in his life.
And though he was blessed with abundant talent, fate was never kind to him.
The two shining lights in his life were his mother (Julie Walters) and wife, Julie-Ann (Alexandra Roach), who wholeheartedly supported his endeavours.
The roller-coaster ride that was his life was never destined to bring the adulation and success Potts craved.
He thought his dream was gone and a life in Wales running a mobile phone shop was his present and future.
But crippling debts and the chance to win 100,000 ($195,000) drove Potts to take the biggest step in his life - to enter the TV series, Britain's Got Talent.
His initial performance of Puccini's Nessun Dorma in front of Simon Cowell has been watched more than 15 million times on YouTube and has become the stuff of folklore.
So his future was sealed.
One Chance is simply a wonderful story beautifully told.Craig Nicholson
