Cocktail Party Physics, where I got the "NEA 100" (which I am currently working to update), has posted her choice of 75 top popular-science titles. Many good additions to the list in the comments, too.
(Real science, not sci-fi, but I couldn't resist this picture I came across, because I am very fond of parrots.)
I'm thrilled that I have read any of CPP's choices, at all:
20. The Physics of Star Trek, Lawrence Krauss (I'm not quite done, but almost!)
41. The Periodic Table, Primo Levi [this goes on my top 100, period]
69. Copenhagen, Michael Frayn (saw on stage)
But--darn--haven't seen any of them as movies.
