I was talking with my son about understanding how to breakdown a movie right around the same time that I found this amazing video essay on subplots. I am a huge fan of Lessons from the Screenplay. If you want a good understanding on how to break a movie into its individual parts this is the channel to watch.
In this case my son and are were trying to get a good handle on how to break a movie into a three act structure. Understanding subplots is the next level and this video does an amazing job explaining it.
