Carla Gugino has officially signed on for Mr. Popper's Penguins, according to a report at Variety.

Gugino, best known for her appearances in Sin City and Watchmen, will act opposite Jim Carrey in the adaptation of the classic children's book by Richard & Florence Atwater.

Carrey will play Mr. Popper, a house painter whose dreams of Arctic exploration prompt him to write letters to real explorers. When one of them responds with a gift of one dozen penguins, Popper is left with the challenge of dealing with the Arctic birds. Soon he opens a stage act called Popper's Performing Penguins and goes on tour, creating mayhem at every stop.

Though Gugino's role is unspecified, the book does feature a female lead in the form of Mrs. Popper, the hero's wife who helps to deal with the penguins.
