In a land ruled by mad scientists, each with a loyal assistant, an Igor, whose job can be summed up in two words: “Yes, Master,” one forward thinking and talented hunch-backed Igor (voiced by John Cusack) dreams of becoming an inventor himself and winning the annual Evil Science Fair.

Lending their vocal talents to Igor, an offbeat and winning animated feature, is the irrepressible Molly Shannon as Eva, a monster with a heart of gold, Steve Buscemi and Sean Hayes as Igor’s bumbling compatriots and the always fabulous Jennifer Coolidge proves she’s hilarious in person or as a cartoon.

Grade: B Igor releases in theaters Sept. 19.
