Cowabunga -- the Turtles are back -- and you can celebrate by entering for your chance to win cool movie prizes in our Entertainment section's contest in conjunction with the Warner Bros. Pictures release of "TMNT."

The Movie
The Teenage Mutant Ninja Turtles return to the big screen as never before in the all-new computer-generated action adventure "TMNT," written and directed by Kevin Munroe.

After the defeat of their old arch nemesis, The Shredder, the Turtles have grown apart as a family. Struggling to keep them together, their rat sensei, Splinter (voiced by Mako), becomes worried when strange things begin to brew in New York City.

Tech-industrialist Maximillian J. Winters (Patrick Stewart) is raising up an army of ancient monsters, and only one super-ninja fighting team can stop them -- Leonardo (James Arnold Taylor), Michelangelo (Mikey Kelley), Donatello (Mitchell Whitfield) and Raphael (Nolan North)!

With the help of old allies April O'Neil (Sarah Michelle Gellar) and Casey Jones (Chris Evans), the Turtles are in for the fight of their lives, as they once again must face the mysterious Foot Clan, who have put their own ninja skills behind Winters' endeavors.

Making this new incarnation of the Teenage Mutant Ninja Turtles truly cutting-edge, the film was created entirely with state-of-the-art computer-generated animation, giving the Turtles a completely new look for the 21st century.

Rated PG by the Motion Picture Association of America for animated action violence, some scary cartoon images and mild language, "TMNT" opens in theaters nationwide March 23.
