There was a screening of some clips from the upcoming Ben Stiller comedy, Tropic Thunder, at ShoWest in Las Vegas this week. AICN has a great description of the full trailer as well as the two clips that were shown but he doesn't give too much away. I highly recommend reading this article. It seems like everything I read about this film lately has me totally psyched to see it.

For those who don't know the plot, here's the studios official summary:

"When a group of actors shooting a war movie includes Kirk Lazarus (Robert Downey Jr.), an over-the-top Australian-born method actor who has gone to extremes to get into character, novice thesp Sandusky (Jay Baruchel), gross-out comedy star Jeff Portnoy (Jack Black), Four Leaf Tayback (Nick Nolte), the real-life inspiration for the film, pampered action superstar Tugg Speedman (Ben Stiller) and rap star Alpa Chino (Brandon T. Jackson). DreamWorks Pictures Presents A Red Hour Production A Ben Stiller Film "Tropic Thunder" starring Ben Stiller, Jack Black, Robert Downey Jr., Brandon T.
