I don't think there are any movies from the past that I missed that I really care to see now. However, I do like watching some of the old movies from when I was a child (or even from when my children were young). What movies do I like watching again and again? Well, one of my favorites is "The Absent Minded Professor" and the sequel "Son of Flubber." I don't care much for the remake, "Flubber," though. The stories are silly and unbelievable, but they make you laugh. So, if I've had a rough day of a lot of thinking and figuring things out, it's something to relax and get my mind off things.
