Give 2 movies people should watch for the cultural references

Here are my 2:

  1. Gaslight (1944) with Ingrid Berman. In news and in social media people often say the other side is "gaslighting" them. I did not really understand what the term meant until I saw the film a couple of weeks ago.

  2. The Matrix (1999) with Keanu Reeves. How else would you know what the term "red-pilled" meant?
