I don't mean to sound cynical, but I'm not surprised that the new environmental documentaryThe 11th Hour timed the release of a new trailer with the recent Live Earth festivities to capitalize on a little free press. The official MySpace page has the theatrical trailer, with an introduction by DiCaprio himself. The 11th Hour was produced by DiCaprio, and he also narrates. Directed by Leila Conners Petersen, the film's 'manifesto' is to "explore how we've arrived at this moment -- how we live, how we impact the earth's ecosystems, and what we can do to change our course". There is also an official site up and running with plenty of educational resources as well as some extra info on the various talking heads that appear in the film. There is a pretty wide spectrum; from Professor Stephen Hawking, to Ray Anderson, an interior furnishings mogul who has become one of the best examples of how industry and environmentalism can peaceably co-exist.

This is probably a pet project for DiCaprio, who has been pretty involved in a variety of environmental causes over the years, and has been a vocal supporter of Power Point presenter extraordinaire, Al Gore. To be honest, the trailer alone has already scared the bejesus out of me -- and strangely enough, it almost looks like a big-budget action picture -- with the added bonus of emotionally scarring images of penguins overrun by trash heaps and shameful footage of Hurricane Katrina victims. While this doesn't exactly seem like a fun night at the movies, it's the kind of film you almost feel guilty about not watching. The 11th Hour is slated to hit theaters on August 17.
