Tron
In this '80s film, Tron filmmakers decided to throw in an easily-missed Easter Egg. There's one moment where a character is looking at an electronic map, and you can see Pac-man eating his dots. How funny is that!
The Little Mermaid
It seems like there’s always something inappropriate about a Disney film because, if the target audience is children, give the parents who have to watch as well something to laugh at. In The Little Mermaid, during the wedding scene, the priest that marries the couple is a little…well…excited. Once you see it, it's hard to miss.
