One Chance, review - Telegraph Paul Potts, a shy, round-faced Carphone Warehouse manager from Wales with a big tenor voice and wonky teeth, was the first winner of Simon Cowell's television show Britain's Got Talent in 2007. His success illustrated one of the central tenets of the talent show format, that the more unlikely a contestant's path to fame, the more riotously he would be celebrated by the public. Here, the unlikeliness is hyped for all it's worth. The bulk of the film focuses on the manifold ways in which things go wrong for Corden's Potts: his desperately awaited masterclass with Pavarotti, at which he freezes and is dismissed; his dramatic collapse while singing the male lead in an amateur production of Aida; his bicycle accident, which crashes him into a long depression and mounting debt. Yet the balance here feels oddly skewed in favour of failure, like an advertising poster in which the designer started by writing the word "disappointment" in large, eye-catching letters, leaving only a small space to squeeze in "joy." And so triumph finally gushes into a diminutive gap, with a rerun of Potts's BGT audition, in which Corden lip-synchs to Potts's actual voice, intercut with genuine footage of the judging triumvirate of Simon Cowell, Amanda Holden and Piers Morgan, histrionically turning from sceptical to overwhelmed. Potts's ultimate winning of the entire competition, his successful album, his performance in front of the Queen, and delicious attainment of financial stability are all squashed hectically into the tail end of the film. Call me a teary-eyed sentimentalist, but - having spent so long immersed in the depths of hopelessness - I would have liked just a little more time to splash about in the shimmering shallows of success.
