With production set to begin on the sequel to Teenage Mutant Ninja Turtles 2, news is coming almost daily about casting and potential plot lines. We found out a few weeks ago that Casey Jones had been cast for the film, and that Bebop and Rocksteady would be in the film as well. Today we find out that Tyler Perry will bring a key character to life in Baxter Stockman. In the comics and animated series, Stockman is an African American scientist who is responsible for creating, among other things, the turtle-hunting Mousers.
