I'm amazed at the fanboy rage in the other thread when we haven't even seen any footage yet. I grew up with the tv show, watched the 1st movie in theaters a couple times, have the toys, etc, etc. Personally I'm stoked that we're even going to get a live action movie. I understand they gotta do whatever they gotta do to make it work in live action, and deals with car companies have to be made to fund the movie. Only Lucas has that kind of fuck-you money. If Bay and company can honor the core of the characters like others have with Spidey and Xmen, I'll be ecstatic.
Anyway here's a pic of the on-set Bumblebee animatronic that Aint-it-cool got.
(The picture is huge, so I'll just link to it)
D'OH! The studio made them take down the pic, although I've seen it in several places around the net. With a little searching you can find it.
