QUOTE
Five years ago Dennis (Simon Pegg) was at the altar about to marry Libby (Thandie Newton), his pregnant fiancee. He got cold feet and ran for the hills and he's been going in circles ever since. When Dennis discovers Libby's hooked up with high-flying-go-getter Whit (Hank Azaria), he realises it's now or never. He enters a marathon to show he's more than a quitter, but then finds out how much sweat, strain and tears it takes to change. Nobody gives him a chance but Dennis knows this is his only hope to be more than a running joke.

The Run, Fat Boy, Run premiere will be held on 3rd September at the Vue, Leicester Square in London, UK.

You can also catch Simon on Friday Night With Jonathan Ross on BBC1 on 7th September as confirmed by the BBC.
