Zoom is a 2006 American superhero comedy film based upon the children's book Amazing Adventures from Zoom's Academy by Jason Lethcoe. Directed by Peter Hewitt, the film stars Tim Allen, Kate Mara, Spencer Breslin, Michael Cassidy, Kevin Zegers, Courteney Cox Arquette, Chevy Chase, Ryan Newman, and Rip Torn. Decades prior to the start of the film, the American military sponsored a superhero group called "Team Zenith." Its leaders were Jack Shepard, a.k.a. "Captain Zoom", who possessed super-speed, and his brother, Connor, a.k.a. "Concussion", who could project sonic blasts. The military tried to increase the team's powers by exposing them to an experimental form of radiation called "Gamma-13". This caused Concussion to become more powerful, but it also reversed his personality and turned his eyes red, thinking Zoom and the team betrayed him and went insane. Concussion killed his teammates Marksman, Ace, and Daravia. Concussion was believed to be killed by Zoom in an explosion, but he had been sent into another dimension instead. Zoom lost his powers, and his brother. Thirty years later, Dr. Grant, the scientist behind the original Zenith Project, discovers that Concussion is making his way back into their dimension.
