One detail from the book that didn't make it into the movie that I think is neat is that Eva Stratt did not just stumble across Ryland Grace. He was not the 'potentially disposable' option. She went to the top microbiologists in some of the best research labs in the world and was told multiple times "you know what? I think Dr. Grace might be your guy." When discussing the Petrova Problem. And this several years after his ejection from academia.
