What's your favorite Hemingway novel? It's amazing to think that he was friendly with Castro!
For whom the Bell Tolls
Have you seen the movie version? It has Gary Cooper and Ingrid Bergman, among others. They made it in the early 40's!
I usually rather read the books because it frees my imagination, instead if you see a movie you are seeing the director or screenwriter perspective of the book 
That's a really interesting point. It's fascinating how attracted Hemingway was to Spanish culture and politics. Though he was an American icon, a lot of his writing focuses on such themes.
Hemingway influenced many people because he was an amazing journalist and by that time Castro was a person who attracted a lot of people because the disaster he created in Cuba and now in Venezuela had not yet seen 
That's quite astute! On that point, have you made it to the Hemingway house in Cuba? They restored it about fifteen years ago.
I have never been to Cuba neither expect to go there while this communist regime runs the country but I have been to Hemingway' Key West House. It is really awesome the feeling you get when you visit his house 
Did you make a pilgrimage to Sloppy Joe's when you were in Key West? They're still fighting over which one was the original!
Yes! this is a classic thing to do in Key West, but the town has plenty of things to do and very interesting sites to visit. I want to go back soon
