Friends star David Schwimmer goes behind the camera for this hilarious directorial debut that proves love is not a sprint its a marathon.

Simon Pegg, the comedy star from the outrageous Shaun of the Dead and Hot Fuzz is Dennis a man on the run... from the altar. He is bolted, leaving his pregnant fiance (Thandie Newton) crying at the chapel and everyone else baying for his blood. Now five years later, dead-end Dennis wants to make up for lost time and prove he is the marrying kind and a good dad to his devoted son. Out of shape, out of time and out of options Dennis has to contend with his exs smarmy new boyfriend (Hank Azaria)... as well as a marathon to run.

While he attempts to drop the fat and pick up his game, will Dennis finally cross the finish line and become the man nobody believed he could?

Also starring cult comedian Dylan Moran from Black Books, Thandie Newton from Crash and Hank Azaria from Dodgeball.
