The dudes who penned the Transformers script are backing away from the minstrelbots:
Cole: I heard that the gold tooth was Michael Bay's idea, but do you have any response to those who found The Twins offensive?
Orci: Number one, we sympathize. Yes, the gold tooth was not in the script, that's true.
Kurtzman: It's really hard for us to sit here and try to justify it.I think that would be very foolish, and if someone wants to be offended by it, it's their right. We were very surprised when we saw it, too, and it's a choice that was made. If anything, it just shows you that we don't control every aspect of the movie.
Cole: Were you offended by them?
Kurtzman: I wasn't thrilled. I certainly wasn't thrilled.
Orci: Yeah, same reaction. I'm not easily offended, but when I saw it, I thought, 'Someone's gonna write about that.'"
