15 September 2010 Last updated at 15:13 BST

As a boy, Kevin Lewis grew up in an impoverished family on a London council estate. He was beaten and starved by his parents, bullied at school and ended up in care. His story became a best selling book - The Kid. Now it's been turned into a film starring Rupert Friend who explained the role to BBC Breakfast.

The Kid is in cinemas from Friday 17 September.
