So, remember when there was some talk about Trans4mers being a smaller movie than the others? Yeahhhhh, I think not. Watch, if you choose, a video of trains crashing on the set in Detroit, which is apparently doubling for Hong Kong.
Remind me again - was it creative bankruptcy that Detroit filed for?
(Fingers crossed that this video still appears when this post goes live - since Bay himself Tweeted it I can't imagine he'll have it removed.)
