Megan Fox will apparently be joined by Will Arnett in the Teenage Mutant Ninja Turtles film.
Arrested Development and 30 Rock star Will is the latest addition to Jonathan Liebesman's reboot in an undisclosed role, according to The Hollywood Reporter's Heat Vision blog
Megan is already on board to play the turtles' friend April O'Neil, while the turtles will be portrayed by Parks And Recreation's Pete Ploszek, Breaking Bad's Jeremy Howard, Alan Ritchson (The Hunger Games: Catching Fire) and Noel Fisher (The Twilight Saga: Breaking Dawn - Part 2).
Roles yet to be cast include the turtles' mentor and trainer Splinter, their friend Casey Jones and their enemy Shredder.
Michael Bay will be on hand as producer for the film, which will be released in 2014.
Will - who split from funnywoman Amy Poehler last September - will next reprise his role as Gob in Netflix's Arrested Development, and has lent his voice to Batman in Warner Bros' upcoming animated film The Lego Movie.
The 42-year-old will also voice the lead character of Surly the Squirrel in The Nut Job.
