Will Arnett joins Megan Fox in Michael Bay's 'Teenage Mutant Ninja Turtles'

There's another casting announcement for Michael Bay's Teenage Mutant Ninja Turtles, so that can only mean one thing: Somebody really wanted to work with Megan Fox. In this case it was Will Arnett, because what else is he going to do?

The Hollywood Reporter says Arnett is joining the cast in an undisclosed role, although the site claims it will be as the terrapins' rat sensei, Splinter. Just so long as it's not Casey Jones we'll be okay. Watch it be as Shredder. Ugh. Fox is playing April O'Neil, perhaps the most misguided casting since Lindsay Lohan as Elizabeth Taylor.

To be fair, Arnett is probably just doing this to kill time while he reprises his role as Gob in the Netflix Arrested Development project. TMNT is due out June 6, 2014, which will give you plenty of time to go see another movie, or maybe the likely series finale for Two and a Half Men.
