"Run Fat Boy Run" (2008)

Dennis is an ordinary guy. He’s a little overweight and he smokes, but he’s nice, charming and unassuming. However, five years ago, Dennis did something that wasn’t so nice. On his wedding day to his pregnant fiancé Libby, Dennis did a runner. He just couldn’t go through with it. He didn’t think he was good enough for Libby, so instead of ruining her life, he ruined her big day. Now, five years later, Dennis realizes he made a big mistake. He’s still in love with Libby. He still sees her all the time because of Jake, their five-year-old son, but all romantic ties have been severed. Libby’s now seeing Whit, a charming professional from the City, and Dennis takes an immediate dislike to him. Whit is casual, easy-going, successful and good with Jake; much to Dennis’s annoyance. How can Dennis compete with him?
