Expecting a comedy from Mexican director Alejandro Gonzalez Inarritu would have preposterous. The man was known for his cinema verite of suffering, notably Babel, 21 Grams, Biutiful, and his best film, Amores Perros, roughly translated to Love’s a Bitch. Perhaps there isn’t much of a shift going from tragedy to comedy. Inarritu’s newest film, Birdman or (The Unexpected Virtue of Ignorance), has been wowing critics and audiences alike, building deafening awards buzz for its cast, Iarritu, and the superb cinematography, but will it fly with mainstream audiences? This may be one of the weirdest Oscar front-runners in some time.

Riggan (Michael Keaton) is an actor best known for playing the superhero Birdman in the early 1990s and walking away from the franchise. He’s still haunted by that role (sometimes literally) and struggling to prove himself as an artist. He’s brokered all his money into directing, adapting, and starring in a theatrical version of Raymond Carver’s short story, “What We Talk About When We Talk About Love.” The show is in previews and about to open its run on Broadway but it’s already got a rash of problems. The leading man needs to be replaced immediately. The supposed savior is famous actor Mike (Edward Norton), an undeniably talented but temperamental actor who pushes buttons to find some fleeting semblance of “truth.” Mike’s girlfriend, Lesley (Naomi Watts), is growing tired of his antics and desperate for her own long-delayed big break. Laura (Andrea Riseborough) is Riggan’s “girlfriend” and co-star and may be pregnant. Sam (Emma Stone), Riggan’s personal assistant and also his detached daughter, is fresh from rehab, and spiteful against her neglectful dad. Toss in Riggan’s best friend/manager/play producer (Zach Galifianakis), Riggan’s ex-wife (Amy Ryan), and a feared theater critic (Lindsay Duncan) who is determined to kill Riggan’s show to send a message to the rest of Hollywood polluting the integrity of the theat-tah. Oh, and throughout all this, Riggan hears an ominous voice that alternating encourages him and humiliates him.

It’s an industry satire, a bizarre comedy, a father/daughter drama, an examination on identity and the complicated pulls of affection and admiration, and a stunning virtuoso technical achievement. As a movie, Birdman is hard to pin down or categorize. It’s a movie that you definitely need to experience on your own rather than have described (don’t stop reading, come back…), and that is a reason enough to see the film, a rare aspect among modern movies. It’s an artistically offbeat movie and yet it ultimately is about one has been actor looking back on his career and coming to terms with his own impact with pop-culture, art, and his family. It’s about a man struggling to find his place in his own life, beset at all odds by doubters and traitors and obstructionists. The refreshing aspect about Riggan is that he’s a has-been but not a sad sack; he’s fighting from the beginning, sometimes pathetically and sometimes in vain, but the man is always fighting to regain his dignity, to reclaim his life’s narrative, and to fight for his legacy. Riggan, after all, set the stage for the modern superhero industry that currently dominates Hollywood bean counters. He was too just soon, and the parallels with Keaton (Batman) are superficially interesting but there’s more of an original character here than a reflection of the actor playing him. He’s neurotic, egotistical, hungry, and fighting for respect, like many actors, and the film flirts with the façades people inhabit. Many of the characters are emotionally needy, desperate for validation wherever they can find it.

Another strength of the film is that it finds a moment for each of its talented ensemble players to shine, chief among them Keaton. The actor hasn’t had a showcase like this in some time and he is a terrific guiding force to hold the entire story together. Whether it’s marching in his tighty whities or working through his complicated degrees of neuroses, Keaton is alive in a way that is electrifying. We see several highs and lows over the course of two hours, some moments making us cheer on Riggan and others making us wince, but he comes across more like a person than just the butt of a joke. It’s also just fun to watch him adopt different acting styles when he steps on stage, including one early on where he’s purposely too stilted. It’s so comforting to watch Norton (The Grand Budapest Hotel) get to be great again, not just good but great. Early on, you see the appeal of Mike, his allure, and Norton keeps pushing the audience, as well as the characters, back and forth with his wealth of talent. Stone (Amazing Spider-Man 2) spends most of the film as the sulky daughter but she gets to uncork one awesomely angry monologue against her loser dad. The thawing father/daughter relationship ends up supplying the film with its only degree of heart. Watts (The Impossible) is comically frazzled for the majority of her time but gets a memorable character beat where she breaks down in tears, realizing her dream of “making it” might never materialize. Riseborough (Oblivion) also has moments where he sadness and vulnerability cut deep. The supporting characters aren’t terribly deep but they all have a moment to standout.

It’s a decidedly offbeat film that dips into the surreal though never dives completely inside. The movie is rather ambiguous about whether or not the fantastical flourishes are a result of Riggan being mentally ill, or at the least overtaxed with stress. Is there really a Birdman or is it a voice in his head, a manifestation of his ego or a ghost to remind him of the past when he was a star? Does Riggan really have the powers he seems to believe he does, including the ability to make objects move with his mind? Innaritu playfully keeps the audience guessing, treating the bizarre in an offhand manner reminiscent of magic realism. The bizarre embellishments blend smoothly with the film’s darkly comic tone. It’s a funny movie but one that you laugh at between clenched teeth.

Is it all the unblinking camerawork a gimmick? I don’t think so. While the story can engage with its weirdness and surreal unpredictability, the long tracking shots bring a heightened reality to the unreal, they bring a larger sense of awe to the proceedings, watching to see the magic trick pulled off to the end. If anything, it’s an extra thrill to the script and greatly compounds the artistic audaciousness of the film, but I think it also channels the live-wire energy of theater, of watching actors have to walk that tightrope of performance and blocking, weaving together to pull off the ensemble. It makes the film medium feel more like live theater. Thematically I think the style also connects to the anxious mentality of Riggan. In the end, I don’t truly care that much whether it’s a gimmick or not (though I vote it is not) because the camerawork is rapturous. Made to resemble an entire two-hour tracking shot, it is a joyous thrill to watch these technical wizards do their thing, to watch the best in the business perform a visual magic trick over the duration of two hours. Even if you don’t care for the overall movie you can at least be entertained by the imaginative and thoroughly accomplished cinematography by Emmanuel Lubezki, fresh from his Oscar for Gravity and who should be clearing shelf space for the next bushel of awards he’s destined to win with this film. It’s an intoxicating experience to behold, though the film is structured into 10-minute or so chunks for feasibility. If you want to watch a real cinematic magic trick, check out the film Russian Ark, which is an entire movie, performed in one uncut single tracking shot.

I’m still wrestling with the debate over whether Birdman is an artistically ambitious romp or a truly great movie. Much like the characters in the film, I’m wrestling with whether I have confused my admiration with adoration. It’s a movie that I feel compelled to see a second time, and maybe a third, just to get a handle on my overall thoughts and feelings. That may be a sign that Birdman is a film for the ages, or maybe it’s just a sign that it’s not as approachable and denied a higher level of greatness by its obtuseness. Inarritu’s surreal showbiz satire is plenty entertaining, darkly comic, and a technical marvel thanks to the brilliant camerawork. The percussion-heavy musical score is another clever choice, naturally adding more urgency and anxiety to the proceedings. Birdman is a strange and beguiling movie, one that deserves to be seen, needs to be experienced, and stays with you rolling around in your brain. That sounds like a winner to me.
