One movie that I really enjoyed and found that few people have heard of it is "Timescape" that came out in 1992 with Jeff Daniels and Ariana Richards both giving great performances. Kind of a different time travelling movie that has tourist visiting famous man-made and natural disasters:

It's nice to see Ariana Richards has become quite the accomplished artist:
