He said: "When you see this movie, kids are going to believe, one day, that these turtles actually do exist when we are done with this movie. These turtles are from an alien race and they are going to be tough, edgy, funny and completely lovable."
Naturally, fans weren't too happy to hear that the turtles were now going to be 'an alien race' and there was a lot of negative feedback.
Michael Bay has now responded to the feedback on his official site with the following:
"Fans need to take a breath, and chill. They have not read the script. Our team is working closely with one of the original creators of Ninja Turtles to help expand and give a more complex back story. Relax, we are including everything that made you become fans in the first place. We are just building a richer world."
Paramount Pictures is planning a December 25, 2013 release date for the film.
