Transformers 3 hit the Windy City in a big way today. Lots of photos from the set have popped up all over the web. The highlight of it all has to be the glorious return of the trailer. Optimus Prime has classically been a big rig, and the original Prime of course pulled a trailer (that disappeared at a moment’s notice). The above video, captured by a fan with a phone handy, shows the heroic Autobot leader racing into battle without hesitation.

As for the Chicago set photos… well this might get into spoiler territory, so I’ll leave those after the cut. I must stress that you’ll only see CARS, we don’t know if they’ll become robots or what robots they’ll become.

UPDATE: Here is a video of some of the other cars heading toward the set:

PrimeTrailer

The big guy in all his glory. Will the trailer be used a Transport for other Autobots? NEST Soldiers? Or will it combine with Prime to rival his Jetfire teamup?

Sideswipe

Sideswipe goes topless. Hopefully he’ll get more screen time this movie, he’s a one of the more interesting Autobot designs…

Ferrari

This Ferrari Italia 458 has been spotted on set before, and we’re pretty sure its an Autobot. Any theories as to who it might be? Rodimus?

Stunticon1Stunticon2

Here is where it gets crazy. Who are these guys? Popular theory is they’re Stunticons, call back to the team of car Transformers the Decepticons introduced to combat the Autobots on the road. But these guys are armed every which way imaginable. One wonders if they show up as NASCAR style racers and all these guns pop out for battle. Also, they’re pretty menacing looking so its likely they’re bad guys for the scene they’re shutting down half of Chicago to shoot.

twins

It can’t all be good news. Here are the Twins, Skidz & Mudflap, though we’ve been assured over and over their role is much smaller and hopefully their act has been cleaned up.
