Here’s a collection of snippets of movies where maths appears in one way or another. A few notable ones are missing perhaps due to the unavailability of clips. A few off the top of my head are Good Will Hunting, A Beautiful Mind and even High School Musical! It’s good to see suspect X being featured.
It will certainly prove useful if the author has the energy to keep updating his website. One excellent site on math in fiction by Alex Kasman has been going strong for many years.
