I don't really know, but on some sites I've been on, it said only 2 weeks, but I guess it all depends on how many people go to see it. But also, on the commercials, it says for a limited engagement, so I don't really know.... But it should be out till the 14th.
I'm not sure exactally. I know I seen it twice already! I saw it on the IMAX screen last night and loved it! I could feel as I was part of movie espically in some parts. I felt the rumbling of the ship as it was sinking,that's was kind Scarry! I even felt cold chills as parts of the cold water was comming in ship.
