Indiana Jones and the Kingdom of the Crystal Skull is slated for a Memorial Day 2008 release. We've known that for some time now, but we haven't known when the first trailer would premiere... until now!

CHUD.com is reporting that the much-awaited trailer to the fourth Indy flick will premiere online at 12:01 a.m. on February 15.

The site was told that Entertainment Tonight would show teaser portions of the trailer on their Feb. 14 episode and that, oddly enough, the trailer will premiere in theaters on the 14th, which is a Thursday, as well. We're not sure what the strategy behind that is, but that's what we were told.

So, if you normally see movies on Thursday's, I suppose you're good to go, otherwise, you'll have to wait and see it online on the first minute of the 15th.
