And submitted for your approval:

102 Indiana Jones and the Last Crusade (1989). It's just really good. I mean, Harrison Ford, Sean Connery, guys getting run over by tanks, a cameo by Hitler, an 800-year-old man and sex on the floor (with Indiana Jones!) in Venice! What else do you need?
103 Being There (1979). Peter Sellers in an eerily vivid impersonation of George W. Bush. Naw, just kidding. But this is a must-see.
104 Austin Powers: International Man of Mystery (1997). Pardon me for loving this movie--and its sequels--way too much. And if you can't take that, try Casino Royale (1966?), also with Peter Sellers (and Woody Allen!).

I watched a lot of those in school. My mother's three favorite movies are, alas, not included: The Thornbirds, Somewhere in Time (with Christopher Reeve and Jane Seymour--sappy time-traveling) and Pretty Woman. I guess there was a ban on TV movies--and Julia Roberts, come to think of it... And there's a bunch of things there that I really ought to have seen--Taxi Driver, Raging Bull (Bobby DeNiro, ooh), The Pianist. I guess most of these are on cable...
