Arnett Joins “Turtles”

Another human is joining the cast of the rebooted Teenage Mutant Ninja Turtles.

Actor Will Arnett has signed on for the production.  Arnett will have a lead role in the film, though details on his role are being kept under wraps.

Arnett joins Megan Fox who was cast as April O’Neil last month.

Still uncast from the Ninja Turtles mythology are Splinter, the turtles’ sensei rat, and the villainous and masked Shredder. Arnett is not playing the turtles’ human friend Casey, another role that has yet to be cast.
