Super 8 movie trailer, top secret J.J. Abrams-Steven Spielberg project revealed

It may be a rare case where the trailer upstages the main attraction.

Paramount officially admitted the existence of “Super 8,” a top secret J.J. Abrams-directed, Steven Spielberg-produced sci-fi project, that conspiracy theorists on the Web have been gushing about for the last few days Variety reported.

The first teaser trailer leaked on the Internet a few days ago is now being shown to the general public before “Iron Man 2,” in theaters Friday.

Abrams’ plot is a mystery, although Variety quotes insiders as saying it’s very influenced by the “Lost” co-creator’s love of Spielberg’s ’70s sci-fi movies. Early speculation among bloggers was that the movie was a sequel to 2008′s “Cloverfield,” but Abrams has shot down those rumors, according to Deadline.com.

The trailer hints at an alien presence, with the ominous an intro: “In 1979, the U.S. Air Force closed a section of Area 51. All the materials were to be a transported to a secure facility in Ohio.”

Then there’s a cut to a massive, breath-taking collision between a train and a pickup truck – and a close-up of an overturned Air Force container car with something patently not human smashing its way free.

Fans are clamoring to get into movie theaters.

“This sounds absolutely fantastic,” wrote Harry Knowles on his site, Ain’t It Cool News. “SHOW ME THE MOVIE NOW! LOVE IT! That’s literally all I need to ever know about the movie. Right there. Enough. Show it. Now.”
