The hysterically funny, best-selling book comes to life in this smash-hit family comedy! Greg Heffley is headed for big things, but first he has to survive the scariest, most humiliating experience of any kid's life, middle school! That won't be easy, considering he's surrounded by hairy-freckled morons, wedgie-loving bullies and a moldy slice of cheese with nuclear cooties!

Prepare yourself for the wrath of the Norsemen! That is, if you don't mind and it's not too inconvenient...Everyone knows Vikings are ruthless barbarians whose idea of a good time involves pillaging, plundering and feasting. But Thorfinn is no ordinary Viking! He is always polite and happily offers to wash the dirty dishes. Too bad his dad is Harald the Skull-Splitter, Village Chief and the roughest and toughest Viking of them all. On a raiding voyage...

When Greg Heffley's dad threatens to send him to military school if he doesn't stay out of trouble, Greg finds all-new ways to land himself in the doghouse! For starters, Greg's in over his head when he pretends to work at the swanky country club where Rowley's family has a membership. Things don't go much better on a father-son camping trip with the Wilderness Explorers, and then there's the Heffley's new dog, Sweetie, who fetches even more trouble...
