Martin Scorsese's Shutter Island opens in less than a week and a new behind-the-scenes video has popped up, which you can check out after the jump. The creepy mental hospital pictured in the video is the setting for Laeta Kalogridis' story about two U.S. marshals who investigate the mysterious disappearance of a murderess from a hospital for the criminally insane, that looms like a fortress on the island.

Shutter Island stars Leonardo DiCaprio, Mark Ruffalo, Ben Kingsley, Michelle Williams, Patricia Clarkson and Max von Sydow. Adding to the sinister atmosphere are Elias Koteas and Ted Levine--yes! Platinum Dunes' new Freddy Krueger, Jackie Earle Haley, also has a role.

The film is based on Dennis Lehane's book of the same name and contains many of the things Scorsese loves to play with: psychological twists, suspense and pulp/noir-ish tough guys. I've heard some horror fans arguing that this is more of a thriller and less of a horror film, but judging from the trailer alone there is enough evocative imagery and Gothic sensibility that makes the horror grade A-ok for me. Is anyone else reminded somewhat of Cronenberg's Spider?

Shutter Island opens in theaters Friday, February 19.
