There are loads of disaster films, from classics like 'Towering Inferno' to 'Armageddon', the genre being based on hypothetically possible events rather than any specific real one. Then there's the increasing popularity of feature length documentaries, that people are more and more willing to pay to see in cinemas, like the work of the excellent Nicolas Phillibert, or Michel Moore, Morgan Spurlock etc. Also, the influence of reality TV?
Put all that in a pot, mix well, give to Hollywood producers, and you get 'Hurriane Katerina: The movie'?
P.S. Didi, relatively speaking, New Orleans is on Hollywood's doorstep, whereas Indonesian Tsunami is not. What! cynical - me?
P.P.S. Ben, when you say "I'm like Eric Bana, and would reccomend Chopper", do you mean you like Eric Bana generally but particularly recommend Chopper as a film that has him in it, or that if anyone wants to get a better idea of what you're like/look like then Eric Bana in Chopper is THE reference movie?
