Given the success of the previous TMNT film, there is a sequel coming up. It is revealed that the subtitle for the sequel is going to be half shell. The previous movie wasn’t really critically acclaimed. Also, fans of the source material may feel a little insulted at the new turtles. As far as the plot, there is little to nothing revealed about the upcoming Turtles sequel. The only thing that is known is that Bebop and Rocksteady will appear.
Economia said this is not all that different from the previous franchise. Back in 1990, Teenage Mutant Ninja Turtles has gotten its first live action adaptation. It was more in line with the original comics. In that case, it was a little bit darker. Some of the things that they have taken from the cartoon was that the turtles wore different colored masks. A sequel was released in 1991 which featured two more mutants who were supposed to be Bebop and Rocksteady, but were instead referred to as Tokah and Razaar.
Teenage Mutant Ninja Turtles: Half-Shell is scheduled to be released on June of 2016.
