Though it's still early and a script hasn't even been written yet, early reports online claim Michael Bay may want to kill off Megan Fox's character in Transformers 3 within the first 15 minutes of screen time. Sources for In Touch Weekly (via popcrunch) say that Bay is "considering writing Megan out of the series in a gory death scene in the first few frames of Transformers 3 and replacing with another gorgeous young actress." They go on to add (from their source): "Michael's pretty much discovered Megan and now he's very quietly looking for her replacement. He hasn't decided if he's going to kill her off in the next movie, but he just wants to be prepared."
To me this sounds like complete and utter nonsense, which may in fact be more spin from Bay's camp, or just something someone randomly made up in order to get more traffic to their site. Amidst Bay and Fox's recent verbal boxing match, I can see how the director may have joked about killing her off in the first scene, though the studio knows how important she is to the franchise and I can't see them agreeing to a move like that since they won't have the obligatory 47 still images of Fox to send out in advance of the film's release. Instead, look for Bay to get his revenge by sticking her in even more obscene outfits while making her bend over in every scene.
Then again, I wouldn't be against a gory Megan Fox death scene in the opening moments. Knowing that was coming might just get me to watch the third installment. You?
