Movies that I will watch again and again

My husband, will watch just about anything, over and over again.  Unfortuantely, we don't have quite the same taste always.  For example, a couple of Mr. G's go to reruns are Dune and Waterworld.  He calls these "classics", I called them weird. Other must re-see movies include Apollo 13, Dave, Star Trek and Star Wars, Tremors, and that sci-fi movie with Bruce Willis with the girl with pink hair.  These are not necessarily moives that I would pause for as I scan through channels on the TV.  So, I started thinking about movies that I would pause for...
My Fair Lady---The costumes are amazing, the songs are fantastic, but I think my favorite part is Audrey Hepburn yelling "move your bloomin' arse!" at the race horse.
The Music Man (the original)----just love the music on this one
Yours, Mine and Ours with Lucille Ball----love it, even though I have seen it dozens of times
White Christmas with Bing Crosby and Rosemary Clooney---have to see it every year, it is my Christmas tradition..
Talladega Nights with Will Farrell----yeah, I know this seems out of place given the top of this list.  My absolute favorite scene is when he is in the bar with Amy Adams explaining how he is thinking about becoming a nice drug dealer.
The Proposal-----if you have not seen this you have to watch it.  The scene with Sandra Bullock and Betty White "chanting" in the forest made me laugh so hard I almost wet my pants!
Doris Day and Rock Hudson movies
IronMan1 and 2 and Sherlock Holmes and really just about anything with RDJ
