We're here, Joaquin Phoenix is still here, and now the trailer is here as well. Yes, the trailer for I'm Still Here has popped up online, and now we all know whether Joaquin Phoenix is now faking it, serious, or just mentally disturbed.

Only kidding - we still don't have a clue. The teaser for the mockumentary/rockumentary/mental breakdown documentary, directed by Casey Affleck, doesn't answer the question at all.

Instead, we get shots of Joaquin running between hotels, running on stage, running off stage, and generally being all weird and heavily-bearded. On top of it all, a highly philosophical voice-over ("That's you - a drop of water on the top of the mountain...") which just makes things more confusing.

It's distributed by Magnolia Pictures in the US (no-one's stepped up to do the job in the UK yet), where it'll be released on Friday 10th September. Then we'll find out what's going on. Or at least confirm what we knew all along: Joaquin Phoenix is sliding down the mountain. And is clearly completely off his rocker.

The trailer's online over at Yahoo! Movies, but you can read on for the full video.
