In Her Smell, the unfortunately named new drama from Alex Ross Perry, Elisabeth Moss does something you almost never see in movies about rock ’n’ roll: She sucks all the cool—all the sexiness, all the glamour, all the romance—out of a downward spiral into debauchery. Her character, Becky Something, is the frontwoman of a grunge-rock trio (think L7) that’s slowly inching out of multi-platinum success. When we first meet Becky, it’s at the mic, where she’s still a star, basking in adoration, elating a crowd of faithful fans with a salty-sweet riot-grrrl anthem. This is, as it turns out, a fleeting mirage of charisma. Because from the moment she walks out of the spotlight, we see the real Becky, the one her colleagues and handlers see, the alcoholic diva on the warpath. And Moss attacks the role with a fearless lack of vanity, daring to make this nosediving rock star not just unlikable but downright irritating—as hard to endure as chipped nails dragging slowly down a chalkboard …With Her Smell, Perry offers the alum her meatiest starring role yet, and she sinks her teeth into it hard. Staring out from furious black holes of eyeshadow, her face twisted into a glitter-caked sneer, the actor plays Becky as a tornado of intoxicated hostility, fixing always for a fight. At the same time, there’s an element of performance to her rampages: the rhyming, the alliterating, the insults hurled in a mocking sing-song cadence. Are the drugs and booze talking, or is Becky putting on a show even off the stage? We could be watching Gena Rowlands play Courtney Love in an alternate-universe biopic. [A.A. Dowd]
