Like Denzel Washington in "The Hurricane", these movies are now "50 years old" so because of that (and because I'm currently in a Seventies State of Mind) I thought it was a good excuse to revisit movies I loved from that year and catch up with ones that I hadn't seen yet.
Also, this gives me an excuse to watch "Jaws" again and I'm always looking for an excuse to watch "Jaws" again (seriously, ANY excuse will do).
