There isn’t anything in the laboratory part of the film that hasn’t either been done with a bona fide surrogate or assembled from something that was real.
I hope Ian is right. In science fiction movies liberties are always taken to make the story more compelling and scary. For me this is problematic because non-scientists often think what they see in such stories is real.
I’m sure we’ll have a rousing discussion here about the movie once it is released in September.
