Bleeding Cool sources had this to say about the title change:
"It seems to be driven by marketing. Think of John Carter and how Disney wouldn't allow for a title with either "Princess" or "Mars".
So, it's official? These turtles are no longer mutants or teenagers? "Adult Alien Ninja Turtles" anyone?
Last weekend, Michael Bay revealed that the movie will give the turtles an alien origin, so the removal of the word "Mutant" from the title makes sense. It is still unclear whether the turtles will be teenagers in the reboot.
The TMNT reboot will start shooting later this year, possibly around September, and they are looking for filming locations in Canada.
Sound off on what you think about these "Adult Alien Ninja Turtles".
Teenage Mutant Ninja Turtles comes to theaters August 8th, 2014 and stars Megan Fox, William Fichtner, Will Arnett, Alan Ritchson, Jeremy Howard, Noel Fisher, Pete Ploszek, Danny Woodburn. The film is directed by Jonathan Liebesman.
