What's up with J.J. Abrams' Iron Man 2 mystery trailer?

When theater owners receive their copies of Iron Man 2 this week, one of the film cans will come with a special electronic lock that cannot be opened until Thursday afternoon. Contained within that can will be the first and last reels of the movie, as well as all the trailers that will show in front of it. And one of those trailers, according to Hitfix, is for a secret movie from J.J. Abrams' Bad Robot production company.

The film—which has yet to be shot—will apparently not be directed by Abrams himself, although he was reportedly behind the camera for the trailer. It is also not likely that this is his collaboration with Steven Spielberg, news of which broke last week. So what is it? Well, right now it is going under the title Super 8, and Hitfix is hearing rumors that it could possibly be a sequel—or at least related somehow—to Cloverfield.

As you might recall, an untitled trailer for that Abrams-produced monster movie was launched in front of Transformers in the summer of 2007, kicking off an innovative viral marketing campaign that kept the web buzzing and the hype building for months leading up to its January 2008 release. Whatever you thought of the final product, the run-up to Cloverfield's release was full of the kind of speculation and excitement that comes along all too rarely these days for movies. The flick ended up being a relatively modest hit, but despite on-and-off talk about a sequel, Bad Robot has never officially confirmed one.

Just to add to the mystery, Pajiba reported last November that Bad Robot was secretly developing a movie called 500 Rads (a rad is an "absorbed radiation dose"). The site was told that the movie was in the vein of Cloverfield and 28 Days Later, with a budget in the range of $25 million and a script already being written from an "extensive" Abrams outline.

Could the trailer debuting this weekend be for that movie? Is Super 8 really 500 Rads? No one knows for sure, which is exactly how Abrams wants it. He genuinely relishes bringing the mystery back to the moviegoing experience, and just as with Cloverfield, no matter how the finished movie turns out, you can be assured that he will make the buildup to it as much fun as possible.

So while you have to stay until the end of Iron Man 2 for that film's bonus scene, now it's also imperative to get there early, too!
