The first real trailer for Aeon Flux is available at MTV.com in crappy Windows Media format (it wouldn't even load in Firefox).
I was never a huge fan of the original animated series on MTV (some of the imagery was just a bit too wierd for my taste) but the trailer for the upcoming live action film certainly looks interesting. It follows the old storyline of of an apparently Utopian society where everything is not as it seems.
Visually, the trailer is very cool and Charlize Theron works as the super-spy-assassin character.
The official site, with more background on the story, is here.
