Here’s the first trailer for the Michael Bay produced Teenage Mutant Ninja Turtles reboot. The Turtles don’t look as bad in motion as they did in stills, but they’re too tall and gangly – they don’t look much like turtles.
It looks like the origin story they’re going with is that Shredder made the mutigen that created the Turtles, adding the wrinkle that their creation was his intention (though presumably for some other purpose). This is vaguely reminiscent of the first animated series, in which the mutigen was created by Shredder and Krang, but accidentally dropped into a sewer, where it then came in contact with the Turtles.
We already knew that Shredder was going to be a white guy in this version. Leaving aside the racial implications; without the Japanese aspect to the story, why are they ninjas?
