As part of XBox Live's "Play with Fame" program, XBox Live Gold subscribers only have the chance to play Transformers: Revenge of the Fallen with Megan Fox. To play you have to send a friend request to the Gamertag Megan Fox 2009 by 5:30pm EST on Saturday, August 29th. The Megan Fox session kicks off at 6:00PM. Consider it a lottery, many will enter, few will "win" and play with the lovely Transformers actress.
Speaking of Fox, the rumor that she has been cast as Catwoman in Batman 3 has been proven false. The response from her publicist: "Megan is a huge fan of the Batman movies and of director Christopher Nolan but these discussions have not taken place. Thank you for checking." A script is probably months away from even existing which makes it a bit hard to do any casting for characters that may not be in the movie by the time the various drafts are completed.
