Expert advice, the recent pandemic flu and other recent infecious disease occurrences, years of preparation and guidance by CDC and WHO, the ongoing research - all of it should make for a more realistic, fact based movie although it will be about a fictionalized version of an influenza virus.
Of course, I admit to being a fan of this type of movie, and am more than a little interested in infectious disease information so don't go by me! I want to see how they do this, and hope not to be disappointed. I really want them to get it right because a truly lethal fast spreading virus is always an alarming but very possible scenario (think of SARS, and Ebola). Influenza is always going to be with us, and it is a wily adversary worthy of concern. There is so much we don't know yet, and human behavior predicts that we help the spread of these viruses without even knowing it.
The control of information that is talked about in the movie is also very real. Witness what happened in China when SARS was spreading uncontrolled and the Chinese authorities deliberately kept this knowledge from us. Having accurate information saves lives which is why what CDC and WHO did during the last pandemic was watched and commented on by many. Not everything that was given out as fact was proven to be true, and what they did not say was just as important as what they did. I expect recent events will be reflected in the movie.
I would also expect that the film will be more than just entertainment. I would hope that it would also educate about what has happened before and could happen again. I think that there should always be some level of concern about influenza, and that we need to be more aware of the ongoing history of influenza outbreaks, and who is at risk.
