Check out a recent and kinda gross clip from the upcoming comedy “Run, Fatboy Run” by director David Schwimmer and starring Simon Pegg (Shaun of the Dead) and Thandie Newton.

Plot: A chunky, clueless guy leaves his pregnant fiancée on their wedding day only to discover — 5 years later — that she is his one true love. But in order to win back her heart, he looks to finish his first marathon while making her realize her new man is the wrong guy for her.
