'Transformers: Dark Of The Moon' Teaser Trailer Debuts

Preview shows astronauts encountering massive robot craft during 1969 moon landing.

It's big and bad but with surprisingly few 'bots — the trailer to "Transformers: Dark of the Moon" finally premiered online Wednesday (December 8).

The teaser for the latest installment in the high-tech robot saga actually features a lot of footage that many Americans have already seen from the U.S.' historic 1969 mission to the moon.

Scientists in crew cuts and glasses mill about the space center while famed anchor Walter Cronkite narrates the revolutionary event via archival footage. However, in the preview, there is one significant moon discovery that the world didn't see. As the astronauts bop along glacially in zero gravity, they come across an enormous craft that has crashed, which dwarfs the moonmen's spaceship in size and sophistication.

Sweeping shots of the vessel reveal an elaborately constructed enterprise as the astronauts gawk in wonder and confidently report back to the space station that there are no discernible signs of life. However, as the camera dives into the inner sanctum of the craft, the eye of a seemingly out-of-commission 'bot begins to light up.

The franchise's stars have insisted that this is the must-see installment of the series.

"This is, and I'm not just BS-ing you, it's the best movie we've made of the three by far," Shia LaBeouf told MTV News recently. "The script is the best script we've had. The second movie, we were in the middle of a writers' strike, writing on the go," he explained. "The first movie, we had the discovery, and this movie really is the fruition of the rhythm we've created out of five years working together. I'm super proud of this movie."

Co-star Josh Duhamel, who got to check out some of the footage, also gave the flick early raves.

"I've seen about 10 minutes of it — just the stuff we shot in Chicago — and it's pretty awesome," he said in October. "It's all in Michael Bay's head, so you never know what the film's going to turn out like, but judging by the script and what we've shot, it's, I think, every bit as good, if not better than, the first two."

"Transformers: Dark of the Moon" is set to hit theaters in July.
