Michael Bay has an interview with mtv.com.  It’s a good read, check it out here. 

This is my superhero movie,” Michael Bay says to MTV News moments after screening 25 minutes of nearly complete footage from his summer blockbuster “Transformers.”

Additionally, during the preview there were four unfinished scenes shown that have left people stunned.  Here’s some descriptions.

Blackout at the military base
Extended clip showing Deception helicopter Blackout at the military base. The clip shows the Decepticon attacking the military so that he can break into military computers to get more information on the humans. The classic transforming sound is used in the film when Blackout transforms. This scene is very action oriented with the U.S. being taken by surprise and the desert outpost destroyed.
Sam Witwicky gets his first car
After Sam Witwicky (Shia LaBeouf) gets his first car which turns out to be a 70s yellow Camaro. He goes looking for trouble with his friend. After confronting a football jock, he soon has an opportunity to make contact with the hot Mikaela (Megan Fox). Still not aware his new car is an alien robot, Sam is mysteriously aided by his car when it plays sappy music on the radio and then breaks down at what might be described as a make-out spot. The bumblebee air freshener on the mirror and the glitter ball are a nice touch.
Optimus Prime, Bumblebee, Ironhide, Sam and Mikaela
Optimus Prime (Peter Cullen), Bumblebee and Ironhide along with Sam and Mikaela are on a journey to Sam’s house to try and find some object Sam has. This scene is pretty funny as Sam tries to hide the from his dad that he’s hanging out with 3 huge robots. Prime nearly steps on a dog who later shows is displeasure by urinating on Irongide who mutters something about lubricants on his foot. Prime speaks in this clip. Cullen’s voice sounds good. The Robots are very well animated and look very life-like. Later some government organization who are on the trail of giant robots come to the Witwicky home.
Extended Desert Scene
An Extended Desert Scene was shown of the troops encounter with Scorponok. Having to borrow a cell phone from a bystander so they can call the pentagon while fighting Scoponok, Captain Lennox encounters a not so helpful phone operator who requires a credit card number for a collect call before he will put the call through. Eventually, Lennox makes contact with the Pentagon who send air re-enforcements to help send Scoponok back under ground. This gives the folks at the Pentgon their first look at the robots.
