Did You Know?


David Walliams: the man in the bakery. The role is quite similar to "Mr. Mann" in a recurrent sketch from Little Britain (2003). He plays an annoying customer who always comes up ridiculously impossible requests. See more »


When Whit is having his speech on the stairs at Libby's birthday, he is holding a glass in his left hand. In the middle of a sentence, suddenly the glass is in his right hand. See more »


Gordon: Go on then, run!
Dennis: Isn't there some kind of like... special technique?
Gordon: Well... yeah... you put one leg in front of the other over and over again really really fast.

Closing credits shown in (hard to read) foot-prints, as in a marathon runner running. See more »

Alternate Versions

Two words are dubbed over in the version shown on HBO in the United States. (1) While in the bun shop, the little old lady calls Dennis a "prick" instead of a "cock". (2) When Libby is showing Gordon the bathroom, he says that he put on Italian loafers and they "hurt like hell" instead of "hurt like fuck". In both instances, the actor's mouths are clearly mouthing the correct words, which are also shown in the closed captions. See more »

Better in pieces
26 May 2008 | by dbborroughsSee all my reviews

Amusing comedy thats better in its parts than as a whole concerning Simon Pegg who bails on his wedding day to his pregnant fiancé. Several years later as his ex becomes engaged to an annoying Hank Azaria he realizes that he really does love her and decides to run a marathon to prove his love to his girl and that he is a man to himself. Along the way he's helped along by his son and an odd gaggle of friends. I liked this I didn't love it. I think the odd mix of American (director Schwimmer and Azaria) and British (everything else) wobbles the film and keeps Simon Pegg trapped in a nether world between the two. There are these odd tonal shifts as you have say a finely crafted scene of Dylan Moran and his friends playing poker that works like a great Brit com, and then you have some of the scenes with Azaria where the film seems needlessly loud and boisterous in a decidedly American way. Its jarring and it prevented me from wholly enjoying the film. No its not a bad film but its not satisfying. there is much to love, most of the cast is excellent, with Dylan Moran as Pegg's friend a real stand out.For me it was a pleasure not to have him fade into the background as he has done with most of his movie roles. Many of the jokes are laugh out loud funny since all of the pieces are there but it just doesn't come together. Worth a shot on DVD or cable . Though DVD is probably better where the rewind will help you catch the choice lines
