Directed by award-winning filmmaker Tom McCarthy, Disney+’s “Timmy Failure: Mistakes Were Made,” based on the best-selling book of the same name, follows the hilarious exploits of our quirky, deadpan hero, Timmy Failure, who, along with his 1,500-pound polar bear partner Total, operates Total Failure Inc., a Portland detective agency. An elementary school oddball, the clueless but confident Timmy (Winslow Fegley) must navigate the world of adults around him, including his overburdened mother (Ophelia Lovibond), her well-meaning boyfriend (Kyle Bornheimer), his teacher/nemesis (Wallace Shawn) and a school-mandated guidance counselor (Craig Robinson), all in his quest to become the best detective in the world.
