It will be interesting to see how that plays out...Titanic did so well in part because it was in theaters for like a solid year. A year later some people were looking for movies to watch and there was crap out out so they were like 'Fuck it, let's watch Titanic again!".
Since this is 3D it's going to have sky high ticket prices, have limited theaters/screens it can play at, and just simply won't be able to cast an anchor at a theatre and sit there for months because they'll want to open up that space for the upcoming summer popcorn flicks.
