Michael Bay posted on his forums that another change is coming for our favorite ninja reptiles and that would be the name. Instead of 'Teenage Mutant Ninja Turtles', Paramount wants the movie called 'Ninja Turtles'. Below is what Bay had to say:
Paramount marketing changed the name. They made the title simple. The characters you all remember are exactly the same, and yes they still act like teenagers. Everything you remember, why you liked the characters, is in the movie. This script is being developed by two very smart writers, with one of the original creators of Ninja Turtles. They care VERY MUCH about making this film for the fans. Everyone on this team cares about the fans. Just give them a chance. Jonathan the director, is a major fan of the whole franchise. HE'S NOT GOING TO LET YOU DOWN.
