Medium Cool?
No globetrotting, but it mixes fiction and documentary by placing actors in the midst of real news events (which took some foresight). I'm not sure the movie works as a whole or says anything significant, but it was a respectable attempt to do something different.
The chaos and confusion of 1968 is interesting because of the apparent similarities with today. I'll quote someone from IMDb:
> The Film 'Gets' How the World Feels to Me Today
> Everything is running in different directions, the world is breeding crazies, and all the media seems able to do is add paranoia and misinformation to the mix.
Since the movie was rated X upon release, here's the most salacious scene. (It's pretty innocent.)
