Movies show up in grid view that are not in the current folder


I have my movies organized by genre in specific folders.   When I open my Sci-Fi folder in grid view, I end up with a few extra movies that are not actually in this Sci-Fi folder.   (The two examples being Airplane! and Monsters, Inc.)  

I have checked and double checked the Sci-Fi folder and these two movies are not inside.   (I even checked with the Terminal to make sure they weren’t hidden files)

When I play these two movies, they play fine.  Not sure how they are showing up in this folder.  Any ideas?
