The documentary'll be available August 12, just four days after the Michael Bay-ified movie version comes out. Think of it like a palate cleanser.
Here's a description of the documentary from Comic Book Resources:
Work on "Turtle Power" first started in 2009, with the producers stating more than a "hundred hours of interviews from every corner of the turtle world" were conducted for the doc. The trailer contains comments from noted "Turtle" authorities including Eastman, Laird, John Handy from long-time "TMNT" license-holder Playmates Toys and comedian Michael Ian Black, who dropped out of college to play Raphael on a promotional tour.
Produced by Randall Lobb, Isaac Elliott-Fisher and Mark Hussey, "Turtle Power: The Definitive History of the Teenage Mutant Ninja Turtles" is scheduled for release on Aug. 12 — four days following the "Teenage Mutant Ninja Turtles" reboot film directed by Jonathan Liebesman and produced by Michael Bay.
