It's hard being Michael Bay, what with all the money he needs to count and women he needs to objectify. Plus, one shitty, loud, oversaturated three-hour car commercial is as good as the next, so you can't really blame the guy for re-using footage from one in another. He's got robot testicles to design!
For many, the very existence of Transformers 3 is so insulting that it's hard not to feel further affronted by the fact that its director can't even bother to shoot new footage—in any event, as /Film points out, it's not the first time Bay has done this. [via /Film]
