Brain-bending “Shutter Island” a stunner despite faults

Cat, meet Mouse: DiCaprio, Ruffalo and Kingsley star in the imperfect but riveting "Shutter Island."

Dry land, no matter where it’s located, offers some measure of comfort — a feeling of solidity, a foundation for the feet. Water does not. Its mysteries are limitless. Martin Scorsese means to capitalize on this elemental human fear early. Does he succeed? Please. The combination of the gray sky, choppy waves, an ashen-faced detective (Leonardo DiCaprio) and the score — which pulsates with supernatural menace — is dynamite. In these opening scenes, Scorsese yanks us around like marionettes. We’re right where he wants us.

He keeps on yanking throughout this long-delayed, atmospheric Gothic thriller/film noir send-up, perhaps having a chuckle as we labor to wrap our minds around the gnarled plot — much of Dennis Lehane’s tightly drawn novel is retained — and reason out characters who are beyond reason. “Shutter Island” is one of those films where everyone is hiding something; each line of dialogue seems designed to reveal everything and nothing. Listen, in particular, for Deputy Warden McPherson’s (John Carroll Lynch) greeting to the two federal marshals just off the boat: “Welcome to Shutter Island.” His eyes are a little teasing, but his tone says without saying: “You don’t know what you’re getting into.” Scorsese structures “Shutter Island” so that we don’t, either.

Here comes the tough part. To reveal too much of the plot would be criminal, so restraint will be the name of this game. No doubt you’ve heard lots of murmurs (some disgusted) about a twist; do not let anyone reveal it. Two U.S. Marshals, Teddy Daniels (DiCaprio, proving again he’s grown to deserve leading-man status) and Chuck Aule (a meh Mark Ruffalo) hop a ferry to Boston’s Shutter Island, the grim site of Ashecliffe Hospital for the Criminally Insane. (Sublime character actors like the ever-creepy Jackie Earle Haley and Patricia Clarkson get cameos.) It’s their first case together, and they’re an odd pair: Teddy’s a visibly haunted man while nothing sticks to the low-key Chuck. They believe they’ve come to investigate the disappearance of Rachel Solando (Emily Mortimer), locked away after drowning her three children. Though no one at Ashecliffe can or will explain her disappearance, chief psychiatrist Dr. John Cawley (Sir Ben Kingsley) has a theory. “It’s as if she evaporated straight through the walls,” he says. Kingsley’s slight smirk is cause for a few lost hours of sleep.

The investigation may be a sham. Patients and hospital staff may or may not have been coached. A recovering alcoholic, Teddy, still reeling from the death of his wife (Michelle Williams), may be a reliable or an unreliable protagonist. Rachel Solando may or may not have had help escaping her tiny, barred-in room. The only certainty is there is no certainty. So “Shutter Island,” essentially, is 138 minutes of known unknowns wrapped in a damn stylish package. Little Did He Know noir throwbacks rarely looked this good. The predominantly gray, chilly colors — of the island, the hospital itself — provide a terrific backdrop for such a twisted story about twisted people. Shots of Ward C, home to the most dangerous offenders, show a Gothic castle of untold horrors, where every corner is dark and puddled. Here “Shutter Island” very nearly swerves into horror territory. It comes closer with Scorsese’s envisioning of Teddy’s dreams, so bright they shatter the grimness. Not unlike Dario Argento in “Suspiria,” Scorsese uses the camera like a paintbrush, splashing rich reds and golds and greens against Ashecliffe’s walls and the island’s rocky shores. If despair is dingy, then horror is technicolor.

Sometimes the artistry goes too far at the expense of other elements. There are enough continuity errors as to be distracting (one stopped me cold during a white-knuckle scene). The music occasionally overpowers the characters — about whom, by the way, we learn virtually nothing. They are foreboding (Max von Sydow as Dr. Naehring is downright spine-chilling), and yet their emotional impact is nil. Even Teddy, whose story we come to know and whom DiCaprio imbues with repressed grief and palpable heartbreak, only registers faintly. Then again, “Shutter Island” isn’t out to warm our hearts. The film means to play brains and emotions like piano keys, and it does. And in a psychological thriller? Sometimes that’s more than enough.
