Jonathan Liebesman‘s Teenage Mutant Ninja Turtles reboot may be getting pushed back, even though Paramount just released the film’s first full-length trailer a couple days ago.

According to a source connected with production, the film is being pushed back in order to complete necessary reshoots. The source claims that roughly one-third of the film is being completely reshot and that producer Michael Bay is personally overseeing work on the film – which has taken away valuable time from his work on Transformers: Age of Extinction post-production.

The first full trailer for this summer’s Michael Bay-produced and Jonathan Liebesman-directed Teenage Mutant Ninja Turtles reboot has premiered online a few days following its unveiling at this year’s CinemaCon. You can watch it here below.

The clip is framed by narration from William Fichtner‘s lily-white Shredder, explaining to April O’Neill (Megan Fox) how the city has fallen into ruin and chaos and how he and her father tried to stem the rising tide of violence by creating their own heroes. Yes friends, Shredder had a hand in creating the Ninja Turtles.

Curious what the Turtle Van in producer Michael Bay and director Jonathan Liebesman‘s upcoming Teenage Mutant Ninja Turtles will look like? Wonder no more.

A couple of images of the van created for the movie have been snapped, and you can check them both out below.

Back when we found out that William Fichtner, the character actor known for roles in movies like Armageddon, Black Hawk Down, The Dark Knight, and upcoming titles The Lone Ranger and Elysium, had joined the cast of producer Michael Bay and director Jonathan Liebesman‘s new take on the Teenage Mutant Ninja Turtles, many wondered who he might be playing.

The popular guess was the villain Shredder, even though he was of Japanese descent in the original. Another possibility was Casey Jones, the hockey mask-wearing vigilante. But Fichtner himself, in a recent interview, has confirmed that he is in fact playing Shredder.

A little over a year ago, Michael Bay set the internet ablaze with a quote that seemed to indicate that in the Teenage Mutant Ninja Turtles reboot he’s producing, the turtles would have alien origins instead of mutating as we’re all familiar with.

It wasn’t clear if Bay was being serious with the quote or if he was talking about (as director Jonathan Liebesman later reminded everyone) the alien origins of the ooze that mutates the turtles itself (or if he knew what he was talking about at all), but word of fan outrage reaching him led Bay to tell everyone to “chill.”

But as the reboot gets closer to production, Bay has decided to clear things up a bit. Continue reading to see what Bay had to say.
