It has been reported that Megan Fox is first official cast member of the new Teenage Mutant Ninja Turtles live action movie set to be released in 2014.
From TeenageMutantNinjaTurtles.com:
… it was recently announced that well known actress Megan Fox will be joining the cast of the new Ninja Turtles film. Michael Bay himself made the announcement on his website the other day, saying simply that “we are bringing (her) back into the family!” It remains to be seen exactly what role she will fill, but you don’t hire someone like Megan to just sit in the background. If I had to wager a guess, I’d say she is either being considered for or has already won the title of April O’Neill. It only makes sense that they’d want to add some star power to a film that will be centered on the shellraising heroes, if only to add to the marketability of the movie. Whether or not she will play the role of April, just having her attached to the film raises a lot of questions and intrigue about this project.
