Adventure-loving house painter Mr. Popper (Jim Carrey) contends with the problem of having too many penguins in director Mark S. Waters' adaptation of author Richard Atwater's beloved children's book. Shortly after penning a letter to a team of Arctic explorers, Mr. Popper is surprised to receive a penguin in the mail. Later, after making his mischievous new pal a cozy new home in the freezer, the hapless Mr. Popper comes into possession of a playful female penguin as well. Before long Mr. Popper finds himself surrounded by a growing family of the flightless birds, and begins training them to perform in a traveling show dubbed Popper's Performing Penguins. With each new town the show travels to, pandemonium is quick to follow.
