New "Teenage Mutant Ninja Turtles" trailer: More turtles, more Shredder

There's a new trailer out for this summer's "Teenage Mutant Ninja Turtles" movie, and it's got more of everything -- more turtles, more Megan Fox, more Shredder.

Shredder (William Fichtner) narrates the clip, telling reporter April O'Neil (Fox), "People want justice restored to this world. People want heroes, Miss O'Neil. But heroes are not born -- they're created. That's what your father and I were trying to do."

This trailer also gives the best look yet at the four pizza-loving, masked heroes in action, saving the city from chaos and destruction. Cowabunga, dudes.

Will Arnett, Noel Fisher, Johnny Knoxville, Alan Ritchson and Jeremy Howard also star, along with Tony Shalhoub as the voice of Splinter.

"Teenage Mutant Ninja Turtles" opens in theaters Aug. 8.
