Answer:
Several are the concepts of the movie "Contagion", from 2011 and starring Matt Damon, Marion Cotillard, Kate Winslet, Jude Law and other great actors, which can be considered realistic, even more so taking into account the current coronavirus pandemic.
To begin with, the disease comes from China; While currently the coronavirus comes from the same country.
On the other hand, in the film the virus comes from a genetic mutation between bats and pigs, then spreading to humans; while in reality, the coronavirus also arises from bats, while the 2009 H1N1 flu arises from pigs.
In addition, the film talks about a new disease, with a high death rate that ends up causing millions of deaths around the world, as has happened with the current pandemic.
In short, it is a tremendously realistic film, which operates as a kind of prediction about what is currently happening.
