Open Season tells the story of a 900 pound domesticated Grizzly bear named Boog (Lawrence) and a scrawny, one-horned mule deer named Elliot (Kutcher), stranded together in the woods during hunting season. Boog and Elliot must work together to rally the animals of the forest and turn the tables on the hunters. Messing will voice the character of Beth, a forest ranger who rescued Boog as a cub and raised him.
