My criteria: movie depicts courage and/or families positively, or are just fun, plus I never get tired of seeing them.
Oldies:
* On the Waterfront
* Notorious
* Friendly Persuasion
* How Green Was My Valley
* Best Years of Our Lives
* Red River (and some other westerns - I saw a lot of Audie Murphy and Jeff Chandler movies when I was a kid)
* Just about any musical, through the sixties
* Many WWII movies, especially the lesser know ones
* Scarlet Pimpernel (Leslie Howard version)
* Tale of Two Cities (Dirk Bogarde version)
Newbies:
* Master and Commander
* Incredibles
* Team America
* The Patriot
Loved Best Years of Our Lives and Scarlet Pimpernel with Leslie Howard!
Excellent choices!
There is also a wonderful WW2 movie called Dark Blue World that I adored!
