Tyrese Gibson and
John Turturro are set to reprise their starring roles, with
Peter Cullen returning as the voice of
Optimus Prime and
Hugo Weaving returning as the voice of
Megatron.
Ehren Kruger, who collaborated in the writing of the last film, was again involved in the writing. Despite having initially been confirmed for the film, and with the film already into principal photography, it was announced that
Megan Fox would not be reprising her role from the previous two films. With Fox's character Mikaela being dropped, Sam was assigned a new love interest, who will be played by English model
Rosie Huntington-Whiteley. Also,
Roberto Orci and
Alex Kurtzman, having written the last two films, did not return for this installment in the series, which Orci had earlier somewhat anticipated, fearing the duo would "risk getting stale".
[9] Bay has stated this would be his last installment in the series. In May 2011 it was announced that
Paramount Pictures had bumped
Transformers: Dark of the Moon 's release date of July 1, 2011 two days earlier, June 29, in order to receive an early response to footage. It has been announced that
Transformers: Dark of the Moon will be released one day earlier, June 28, in 3D and
