That’s right boys and girls. Danny Woodburn has been cast as the Ninja Turtles’ rodent sage/father in the upcoming Teenage Mutant Ninja Turtles reboot. Woodburn is famously known for his work on Seinfeld, where he played Cosmo Kramer’s angry side-kick. The only major role left uncast is the villainous Shredder. As of now, all we can do is hazard a guess as to who it might be.
