This intermittently wry British comedy from David Schwimmer (best known for TV's "Friends") has gotten the runaround from reaching the silver screen for a while by studio executives.
Run, Fat Boy, Run centers around Dennis (Simon Pegg of Hot Fuzz), a scoundrelous sort who once left his pregnant fiancee Libby (Thandie Newton of The Pursuit of Happyness) at the altar.
Five years hence, Dennis barely gets by as a security guard and as a caring dad to his son Jake (Matthew Fenton) who sees him in a dimmer light.
Pegg, who collaborated on the screenplay, sets up the main conflict through Libby's unctuous, go-getting new Yank boyfriend Whit (Hank Azaria). The "unfit" indolent man will join Whit in a charity marathon in central London, even though it may see him through. He's impelled to prove he's much more than a quitter.
The chain-smoking Dennis isn't fashioned by Pegg with as much viewer friendliness as silly, even if his dolt-like qualities worked better in the aforementioned Fuzz and the cult-hit Shaun of the Dead. Still with Azaria as the high-flying over-achiever and Dylan Moran doing the low-life friend bit to droll effect, Dennis is pegged to have a really good chance at the energetic, comely, often comedic Newton.
Schwimmer generally maintains a light tone with some scenes looking to cross a threshold of ungratuitousness. But, the goofiness generally offsets the maudlin and the predictable as much as one can expect that all of the emotion of the racing and romance comes off with some dignity. Even if the sappy finale isn't hardly as memorable as a bulging blister.
