No, Leonardo and his pals aren't going up against the most fearsome Kaiju of them all, not within the same movie at least. (Though based on some script reviews, that might be a preferable experience.) But the non-teenage non-mutant "Ninja Turtles" are indeed poised to battle it out with "Godzilla" when the two movies are released on the same weekend in two years: May 16, 2014.
Already, the summer of 2014 is finding itself full of alien invasion and other forms of apocalyptic destruction. "Turtles" and "Godzilla" share a release date. There's also "Guardians of the Galaxy" hitting that August. Add to that "Dawn of the Planet of the Apes" and "Robopocalypse," among others, and it's looking like a very eventful summer two years from now.
