Run Fatboy Run

“Love. Commitment. Responsibility. There's nothing he won't run away from.”

Five years after he walked out on his pregnant fiancée on their wedding day, Dennis (Simon Pegg) is still in London, still unfit, and now watching Libby (Thandiwe Newton) settle in with a new man, Whit (Hank Azaria). David Schwimmer directs a comedy about Dennis deciding to run a marathon to win her back, with his friend Gordon (Dylan Moran) in his ear. Dennis has no training and a long record of quitting, and Libby has stopped expecting him to finish anything.
