Given the penchant of the powers that be to race to make movies about 'interesting' real life events, whoever makes the "Miracle on the Hudson" movie is going to be hard pressed to attract viewers.
It's like the dumb ass Valkerie Bertinelli movie with Tom Cruise. Everyone knows how it ends, and without Kate Winslet to lie there nude, who cares about history?
All they can do to try to make "Miracle on the Hudson" interesting is to fictionalize what was going on in the lives of some of the crew and passengers. I don't think they dare make up anything about "Sully" other than to perhaps suggest that he had to go back into the cockpit one last time to retrieve the St. Joseph's bobble head doll he always taped to the yoke. (steering wheel, to the rest of you.)
Screen writers are good at making interesting movies 'based on a true story.' So we can expect a lot of drama in the personal lives of enough crew and passengers so that the eight minutes the actual miracle took can be fortified with 90 minutes of flash back and 10 minutes of expository resolutions. Or they can decide to go with the Al Qeada geese angle.
But really, having "Sully" played by Angelina Jolie, nude, would really, really help.
