Actually not really, but what would you expect with a title like that? It does depend on what you think of Simon Pegg and things like him being exhausted after 10 seconds of running. Also his "wardrobe" and the "handling" of it during certain scenes. Low level humor is what you could call it and depending on your mood or taste, you will like it or you won't like it at all.Simon Peggs character is also not the "biggest" of them all. I haven't watched any of those "Biggest Loser" shows, but I do know there is a difference between the people in that show and what Simon Pegg is having (on his bones). Having said that, not all the jokes work, but it's decent overall.

While the story in "Run Fatboy Run" was good, then this was hardly one of Simon Pegg's best movies. Why? Well, because it just wasn't particularly funny.I must admit that I had higher hopes for this movie, given it being a Simon Pegg movie. Just a shame that the movie was lacking more comedy and funny situations that would make the audience laugh.The story is about Dennis (played by Simon Pegg) who is somewhat out of shape and who ran out on his pregnant wife to be on the day of their wedding. As a new man comes into his ex-fiancée's life, Dennis is forced to take a hard look at his life and himself. So he decides to compete in a marathon to prove his worth.Granted, Simon Pegg did an alright job, he just didn't have any real comedy to work with in the script. But I will say that there is a good bunch of British comedians in the movie. If you enjoy British comedy you will get a kick out of seeing Dylan Moran, Stephen Merchant and David Walliams in this movie.A shame that the movie lacked more laughs and funny moments, because it would have brought the movie out of the mediocre lane.

Friends star David Schwimmer made an impressive directorial debut in this comedic film. The star is Simon Pegg who works at lingerie store as a security guard. He ran away five years ago from his marriage to biracial Libby played wonderfully by Thandie Newton. Libby was pregnant with her son at their wedding that never happened. Well now Libby is dating Hank Azaria's character, a successful American working in London. I love the London film shots. Anyway Dennis Doyle played by Pegg decides to run the marathon. With his friend Gordon and his neighbor, Mr G, who sent him training. Will he give up and quit like he has so many times before. You have to watch and be surprised. It's a great comedy to watch for fun.

Run, Fatboy, Run is the story of Dennis (Pegg) who has never completed anything in his life and also never properly commits to anything and always ends up quitting at the first hurdle. We first see this when he runs out on his wedding, leaving his pregnant wife at the altar. But now, five years on, he plans to win her back by fully committing himself to running a 26 mile marathon in order to regain her love and respect. But he's got competition from the "perfect" man Whit, played by Hank Azaria.Let me start off by saying, I really like Simon Pegg, and I really enjoy all of his films - Shaun of the Dead, Hot Fuzz, Paul, How To Lose Friends and Alienate People. - And this film is included. It was funny at times and had me laughing out loud. Simon Pegg was perfect as this lazy, un-committing "fatboy." And he played his role very well.I'm happy that this film did not resort to obvious, childish sex, dick and fart jokes. It was a quirky comedy and I well enjoyed it. I would recommend it to any Pegg fan or any fan of romantic comedies or quirky comedies. Also, David Schwimmer is a very good director. Who'd have funk it?
