Happy birthday Teenage Mutant Ninja Turtles! April 23 the heroes in a half shell celebrated their 25th anniversary. New York City paid homage to the fictional heroes by lighting the Empire State Building green. The anniversary was also marked by an announcement from Peter Laird that a new live-action film exploring the turtles origins would be released in 2011. No further details are available at this time but hopefully Rob Van Winkle will be available to reprise his role from the second film.
