normal people watching a movie:
aw that was really good and that actor is kind of cute
me:
omfg i must research this movie and it's cast until i know every detail about it/them. i'll know the director and his birthday and his personal life and the producer and everyone involved with production and i shall watch all the other movies all the cast members have been in and i shall love them forever and i will look at pictures of them and watch interviews of them for hours and hours oK
