Despite having been initially confirmed for the film,[9] 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 Banes) being dropped, Sam was assigned a new love interest, portrayed by English model Rosie Huntington-Whiteley. Also, Roberto Orci dan Alex Kurtzman, having written the last two films, did not return for this installment in the series,[10] which Orci had earlier somewhat anticipated, fearing the duo would "risk getting stale".[11] Bay has stated this would be his last installment in the series.[12] 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.[13][14] The film was then released one day earlier, June 28, in select 3D and IMAX theatres, nationwide.[15][16] The film currently stands as the 42nd highest-grossing film of all-time.
