Joaquin Phoenix, what happened? You were such a quiet young man in The Village, and were downright charming in Walk the Line. But with your announcement of retiring from acting in order to become a hip-hop star, people have begun asking questions. Does I’m Still Here have the answers we’re looking for?To start off, his new movie, a documentary (or is it mockumentary? No one’s sure) of his recent life, shares a title with a film he participated in called I’m Still Here: Real Diaries of Young People Who Lived During the Holocaust. Is the naming a joke, a parody of his former reputation as a social activist? If so, I’m not getting it. Following a stint of rehab in 2005, a car accident in 2006, and a bumbling disaster of an interview with David Letterman in 2009, it’s been hard to get a handle on the once renowned actor.After getting a glimpse into Phoenix’s life with the new film (directed by his friend Casey Affleck), people may be sorry they ever wished for explanation. Without acknowledging whether it’s truly a display of Hollywood hedonism or simply an outlandish prank, the film follows Phoenix as he attempts to follow his hip-hop dreams with manager Sean “Diddy” Combs. Nudity, drug use, and other unmentionable behavior assault the viewer in waves. While the whole thing comes off as nothing you’ve ever seen before, whether it’s worth it remains an unanswered question.The film is opening in select theaters on September 10, with September 17. Perhaps as time goes on we’ll get more answers to what exactly is going on here. Until then, if you still want to check out I’m Still Here, proceed at your own risk.
