I'm Still Here — “that Joaquin Phoenix movie” — capitalizes on an anxiety that's very of-the-moment, uniting pop-cultural phenomena as seemingly disparate as the too-stupid/too-good-to-be-true Jersey Shore characters, James Franco's baffling side careers as a professional student and soap opera stud, and pretty much everything having to do with Vincent Gallo. Basically, anything that forces us to ask: Are they fucking with me?

Directed by Phoenix's brother-in-law Casey Affleck, the film purports to document Phoenix's high-profile “retirement” from acting, his alleged attempt to transition into a hip-hop career, and his subsequent, much-publicized meltdown. This period coincided with the promotion and release of Phoenix's last film, Two Lovers, which, like Here, was released by Magnolia Pictures. Whether or not the retirement was contrived or permanent, Phoenix has not appeared in or publicly acknowledged shooting another film since. He also has not released any musical recordings. In fact, he's been all but absent from the public eye since spring of last year — which is, coincidentally, the same time that Here's portrait of his life ends.

At the film's outset, Phoenix describes his acting career as a “self-imposed prison,” claiming frustration with his lack of creative control as a performer (“[I'm] just a fucking puppet”) and resentment over his obligation to maintain his celebrity persona (“I don't want to be the Joaquin character anymore”). And so, after participating in a charity theater event with a “dream team,” including Affleck, Jack Nicholson, Sean Penn and “fucking Danny DeVito,” Phoenix gives a red-carpet reporter the “exclusive” news that this will be his last night as an actor.

It's such an exclusive that it comes as a surprise to Phoenix's publicist, who is helpless to intervene as her twice-Oscar-nominated client proceeds to obliterate any industry goodwill he might have had in a six-month flurry of drugs, shitty rapping, P. Diddy stalking (the hip-hop producer provides much-needed comic relief by riffing on his own persona, as he did earlier this year in Get Him to the Greek) and bizarre public appearances, peaking with Phoenix's now-legendary February 2009 beyond-awkward non-interview with David Letterman. Throughout, Affleck tails Phoenix but largely refrains from intervening in the action, which is enabled by Phoenix's entourage of two, a “general assistant” named Antony and Larry, billed as Phoenix's “caretaker.”

It's hard to doubt the veracity of what's on-screen: Much of what Here depicts happened in real life and in plain sight, and throughout this period the gossip media breathlessly reported on Phoenix's every increasingly curious move. But just after Phoenix announced his retirement, Entertainment Weekly quoted an unnamed source who claimed that Phoenix and Affleck were perpetrating a “hoax” for the purpose of a faux documentary. I'm Still Here was thus the target of skeptical speculation from shot one, a potential liability that Affleck and Phoenix drag into the frame, with Affleck angrily interviewing the EW reporter on camera and Phoenix accusing Antony of selling his secrets.

Perhaps it goes without saying that Here was more provocative when it couldn't be seen, when it existed for most of us purely in the realm of rumor. Despite, say, a report from an early screening that the film included “more male frontal nudity than you'd find in some gay porn,” I counted just two penises, both flaccid and neither filmed more gratuitously than the naked breasts that Phoenix at one point nuzzles, or as graphically as an extended shot including a still photograph of Britney Spears' bare vagina. All of which — like the p.o.v. puke-cam and the many grating scenes of Phoenix berating his paid hangers-on — feels like stock shock tactics, set within a structure too bloated and without rhythm to sustain any sort of sensation. Ostensibly the uncensored story of a life in free fall, Here doesn't offer anything that feels as queasily startling as that Letterman performance.

Think of I'm Still Here's first hour as prologue to that epic event of career self-destruction. By the time Here regurgitates that late-night-TV highlight/career lowlight, Affleck has built enough of a context — about the beleaguered artist whose true identity and actual creative impulses have no outlet within commercial culture — that its impact is inverted. When the studio audience laughs, it's clear they're laughing at Phoenix, which comes off as cruel; Phoenix seems less apathetic or out of it than paralyzed with sadness. And after the taping, he's all too aware of what's happened: “I've fucked my fucking life,” he wails. “I'm just gonna be a joke forever.” With this outburst, I'm Still Here's psychological strategy clicks into place, and its dramatic momentum increases considerably.

Was this all staged? Probably, but does that matter if it feels true? In fact, the end credits more or less confirm I'm Still Here to be, if not a traditional work of fiction, then at least primarily a performance produced for cameras. It seems that this is a secret the filmmakers and their distributor have been trying to protect through cryptic advertising and limited advance screenings (I was required to sign an embargo/confidentiality agreement before entering the theater), hoping to keep the mystery alive. But knowing that I'm Still Here was more invented than accidental raises more questions than it answers.

In other words, the question of whether or not they're fucking with us is easily settled; it's much harder to determine why they're fucking with us. And are they even fucking with us — the average viewer with no direct experience of what it feels like to be a celebrity, who can only make inferences and judgments based on the images that are presented to us — or are they fucking with their fellow celebrities, who stand to feel the force of the less-than-flattering aspects of themselves in Phoenix's portrayal?

Though clearly mocking the delusions of grandeur embodied in one of Phoenix's rap verses — “I'm still real/I won't kneel/I'm the one God's chosen, bitch” — most of the film isn't that broadly funny, or apparently playful. At once deeply felt and devastatingly cynical, I'm Still Here's bone-dry satire couldn't exist without the celebrity media feedback loop. But its apparent attack on the Hollywood machine is so insidery, so vicious, that to us — the everyday consumer — it's just not clear why this stunt needed to exist at all.
