New Trailer for DiCaprio and Scorsese’s ‘Shutter Island’

I remember hearing about this trailer, but I haven't ever seen it-until today. Apple.com put up the official trailer for Martin Scorsese's thriller Shutter Island yesterday and it looks cool!
Island is about two U.S Air Marshall's (Leonardo DiCaprio and Mark Ruffalo) who are addressed to an alien island where an insane asylum has an escaped inmate. It also stars Watchmen's (and new Freddy Krueger) Jackie Earle Haley, Michelle Williams, Ben Kingsley, Emily Mortimer, Patricia Clarkson and Max von Sydow.

Martin Scorsese is directing, and that's a reason to get excited. And since he is, don't expect some stupid "shock endings" like so many movies of the similar genre have had. Shutter Island^nd. Check out the trailer below thanks to CinemaBlend and Shutter Island opens October 2
