Based on the best-selling book series by Jeff Kinney, the film Diary of a Wimpy Kid plays off the painful memories that are as much a part of middle school as algebra. Zachary Gordon stars as the Wimpy Kid himself, Greg Heffley, who has the perfect plan to become one of his school's popular kids. Or so he thinks. By committing the ultimate adolescent social sin trying too hard he practically begs the bullies to come calling.
