When I first heard that they were making a live-action movie of Transformers, the first thing that came to my mind was Mighty Morphin' Power Rangers. "Oh man, it's gonna be horrible!" I thought. "They're going to ruin millions of child imaginations and memories!" I guess we'll find out.
P.S. Authenticity of this trailer has been unverified.
edit: Daniel has explained that the mars vehicle in the trailer is actually the Mars Rover, not the Beagle, leading him to believe that the teaser is fake.
