Five years ago Dennis was at the altar about to marry his pregnant fiancee, Libby, but he got cold feet and ran for the hills—and he's been going in circles ever since.
Now, when Dennis (Simon Pegg) discovers Libby's (Thandie Newton) hooked up with high-flying-go-getter Whit (four-time Emmy-winner Hank Azaria), he realizes it's now or never, so he enters a marathon to show he's more than a quitter—but finds out just how much sweat, strain and tears it takes to run 26 miles.
Nobody gives him a chance, but Dennis knows this is his last, best hope to ever be more than a running joke. For love ...for honor...for a future, Dennis' only hope is to Run, Fat Boy, Run.
Directed by Emmy-nominee David Schwimmer (TV's Friends).
