Movies Everyone Has Seen…But You

I just spent $20 to buy a DVD I feel I HAVE to watch:  "Frozen," the animated musical film from Disney. The movie seems to have taken the world by storm, and spawned a generation that loves the song, "Let It Go."  Because everyone seems to have seen it, I feel like I'm missing out.  I think this is the first time I'm feeling a bit of "cinema peer pressure!"  Another film that I was in the dark about was "Crocodile Dundee" so I finally watched that this past weekend and really enjoyed it!  I'm apparently the type who needs to see a film during its limited run in theatres or else I will miss out.  So now there's a lot to catch up on!  Here's a short list of the films I haven't seen that most everyone has:  "Caddyshack," "Avatar," "Casablanca," "The Graduate," and even "The Hunger Games."  Are there any classics or really popular films that you haven't seen?  Are you missing pop culture references when people mention films like "Ghostbusters," "The Princess Bride," or "Top Gun?"  Let us know in the comments section below.
