1 of my favorites was just on tv, tho it’s not one of the greatest of all time....Bogart & Bacall in Dark Passage.
As for greatest, Gone With the Wind has to be near the top.
My personal Number One Favorite. I even made a pilgrimage to the apartment building In San Francisco where some of the scenes were shot.
One of my very favorites since I was a teenager, as is the book.
I also love “Casablanca,” “The Shawshank Redemption,” “Apollo 13,” and my guilty pleasure is “Office Space.” I laugh out loud at parts of that no matter how many times I see it.
