Shia LaBeouf, Josh Duhamel, Tyrese Gibson, John Turturro and Ram�n Rodr�guez (Ram�n Rodr�guez (actor)) are set to reprise their starring roles, with Peter Cullen returning as the voice of Optimus Prime. Ehren Kruger, who collaborated in the writing of the second film, was said to be again involved in the writing. Despite having initially been confirmed for the film, with the film already into principal photography, Megan Fox will not reprise her role of Mikaela in the film. With Mikaela dropped, Sam is now set to be assigned a new love interest, who will be played by British model Rosie Huntington-Whiteley. Also, Roberto Orci and Alex Kurtzman, having written the first two films, will not return for the third installment in the series, which Orci had earlier somewhat anticipated, fearing the duo would "risk getting stale". Bay has stated that this will be the last film in the series (Transformers (film series)).
