A Bug's Life [DVD] [1999]

Every year the ant colony of a tiny island are forced to hand over their midsummer grain to a marauding band of grasshoppers, led by the evil Hopper (voiced by Kevin Spacey). Worker ant Flik (Dave Foley) sets off to get help from the big city, where he mistakes a troupe of circus bugs for fierce warriors. After being fired by their ringmaster, P.T. Flea (John Ratzenberger), the bugs accompany Flik back to his home, thinking that he is a talent scout. When all becomes clear, they are less than happy at the prospect of fighting off Hopper and his gang!
