"Bad" Mathematics in Movies There's a website and a companion book to it about bad physics in movies, called "Insultingly Stupid Movie Physics". 
Similar issues may exist about mathematics: What are the differences between movie mathematics an real mathematics? What are the misconceptions about the nature of mathematics and mathematicians which may be conveyed to the audience via movies? And so on.
Is there any website, article or book dealing with such issues about mathematics and movies?
Thanks.
 A: I remember watching The fault in our stars which is a great movie, but the wrong math at a very emotional scene, ruined it for me. Shailene Woodley (who has cancer) says this to his boyfriend who also has cancer-

“I am not gonna talk about our love story because I can't. So, Instead I am gonna talk about maths. I am not a mathematician but I do know this. There are infinite numbers between $0$ and $1$. There's $.1$ and $.12$ and $.112$ and an infinite collection of others. Of course, there is a bigger infinite set of numbers between $0$ and $2$, or between $0$ and a million. Some infinities are bigger than other infinities. A writer we used to like taught us that. There are days, many of them, when I resent the size of my unbounded set. I want more numbers than I'm likely to get, and God, I want more numbers for Augustus Waters than he got. But, Gus, my love, I cannot tell you how thankful I am for our little infinity. I wouldn't trade it for the world. You gave me a forever within the numbered days, and I'm grateful.” 

A very good movie but , just saying, if you are not a mathematician, infinities are the first thing you should avoid. 
A: ? Maybe this one : Kentucky Math with Pa and Ma Kettle! .
Or rather this one: Alternative Math | Short Film .
A: Tv Tropes has a page dedicated to bad math in media (not only movies).
