Thanks a lot for the usability feedback! I'm trying to improve it based on this and a few other early comments.

Regarding your question, one limitation I'm aware of is that my data consists mainly of movies _made as historical movies_, not movies that just happen to be set in the contemporary period of when the movie came out. Unfortunately there doesn't seem to be an easy way to identify this latter type of movies based only on wikipedia metadata/categories; so the only way I can think of would be to process _all_ movies on wikipedia and infer whether they are in a contemporary setting... but that's prohibitively expensive. I'll think about it more.
