SAN DIEGO — Typically, a director casts a movie, films it, then releases a trailer to pique everyone's interest. Apparently, no one has explained this to Robert Rodriguez — the Hollywood trailblazer who shot a trailer for a fake exploitation film called "Machete" a few years ago that appeared in the real movie "Grindhouse." Now, "Machete" is about to become a reality, with a huge, strange mix of stars, including Robert De Niro, Jonah Hill and ... Lindsay Lohan?

"I can't say too much about it," Rodriguez teased when we caught up with him at Comic-Con. "Except that we start shooting in a couple weeks!"

If you still haven't seen the "Machete" trailer that he shot with veteran supporting actor Danny Trejo, then by all means check it out immediately. Then, prepare yourself for two hours of the "set-up, double-crossed and left for dead" illegal immigrant who "knows the score, gets the women ... and kills the bad guys!"

"These things come together very quickly. We're casting right now, and the script just came out great," Rodriguez explained of the flick, whose green light was fueled solely by the immense fan love given to that under-three-minute clip. "I was thinking it had to live up to the trailer, because the trailer was so well received. But [the script] far surpassed the trailer."

While the original trailer starred actors like Cheech Marin, the real movie plans to have even bigger stars in on the joke. "We've cast nobody but Danny and Michelle Rodriguez, but we've sent the script out to a lot of people," Rodriguez grinned, despite Jonah Hill's recent confirmation that he's considering a role. "There are a lot of people we're sending it to, big names — but nobody that we've signed yet."

Rodriguez didn't exactly shoot down the rumored name of Robert De Niro, either. "I can't say, you'll have to wait and see," the director said. "Next week, or maybe the week after, probably while we're actually shooting."

The filmmaker did confirm, however, that a certain embattled former teen queen is indeed one of the recipients of his recent script solicitations. "Lindsay's cool," Rodriguez said. "There's actually a cool part in the movie for her — if she takes it."

If it's the part of the senator's daughter, we can't see how Lindsay could say no. But this much seems certain: Once cameras start rolling on Robert Rodriguez's real "Machete," it's going to make for one hell of a commercial.

"The new trailer is going to be magnificent," he promised. "It's going to be really great."
