A live-action adaptation of Jeff Kinney's best-selling illustrated novel, "Diary of a Wimpy Kid" chronicles the adventures of skinny "middle child" Greg Heffley over the course of a school year, as told through his diary and hand-drawn cartoons. Determined not to remain on the lowest rung of the social ladder during his first year of middle school, the hapless Greg takes several stabs at becoming popular -- including betraying his seemingly uncool best friend -- but when his efforts backfire spectacularly, he realizes that keeping a low profile may not be such a bad idea after all. As Greg says, "One day I'll be rich and famous, but for now I'm stuck in middle school with a bunch of morons." Zachary Gordon as Kinney's wise-cracking hero, Greg Heffley. Rachael Harris and Steve Zahn play Greg's quirky parents.
