Doing what he does best, the Cat—voiced by Bill Hader—spreads joy to kids in his hilarious, signature and singularly irreverent way, transporting them on a fantastical journey through a world they’ve never seen before. In the film, our hero takes on his toughest assignment yet for the I.I.I.I. (Institute for the Institution of Imagination and Inspiration, LLC): to cheer Gabby and Sebastian, a pair of siblings struggling with their move to a new town. Known for taking things too far, this could be this agent of chaos’s last chance to prove himself...or lose his magical hat!
