Dennis (Simon Pegg), a clothing-store security guard who abandoned his pregnant bride-to-be, Libby (Thandie Newton), at the altar, looks to win her back five years later. His mission is complicated by her new boyfriend, an arrogant businessman (Hank Azaria) who runs marathons for charity on the side. In order to impress Libby and their son, Dennis pledges to run a marathon, too, with only a few weeks to train. I like Pegg a lot, but this filmwith first-time feature director David Schwimmercant get over its ridiculously stupid and contrived premise. Its saddled with hackneyed, predictable characters (especially Azarias), and their presence distracts from any of the good Pegg is doing. With that said, Schwimmer does show a gift with some of the comedy bits; he could be a decent director with a better script. In other words, even though the film isnt all that good, its decent work for a first-timer.
