I don't see why, everything that could of been done on the subject was done in Cameron's film...
I expect that the subject will be redone now and then, but there won't be much more that can be added. You can only do so much with the Titanic story...
It would be interesting if Hollywood gave the big screen treatment to another shipping disaster. What about a summer blockbuster about the Lusitania sinking. They could call it 'Lusitania'... Doh!
