Although its a year before the movie is scheduled to hit theaters, the first trailer for the Transformers movie is now online. The basic premise: Even though we were all told that the Beagle 2 Mars rover crashed on the Red Planet in 2003, it was actually destroyed by marauding alien robots. (Quoth the preview, It was the only warning we would ever get.) Most of the trailer is an extended sequence of the rover rolling down the ramp for the first time and going through instrument checks, ostensibly taken from an onboard video camera. The detail on the craft is stunning—if you look closely, you can even spot the little USA graphic emblazoned on its wheel hubs.
