The First Full-Length Theatrical Movie Trailer for Michael Bay's big screen adaptation of The Transformers is now online.

You can view the UK version of the trailer online NOW at Yahoo! Movie's UK site. The trailer is more tease then the full reveal fans might be expecting. They land on earth, and when first contact goes horribly wrong we get a few glimpses of actual Transformers in action, and one quick shot of Optimus Prime transforming. Much cooler than I was expecting Check it out now.

Yahoo! Movies intended to launch the trailer at 1:00pm eastern time, but the UK address was leaked to us through an e-mail.

Transformers hits theaters nationwide on July 4th 2007.
