1. This is a movie, folks. Yes, based on a novel, but it was just that - a novel. Uris didn't claim to be writing a history textbook. As with all memorable literature, he tweaked some facts and embroidered his landscape with memorable fictional characters (although yes, many were based on real-life people.) So it's not appropriate to criticize either the novel or the book for not getting every historical fact absolutely right.
2. This is a MOVIE, folks. Based on a novel, but it's still a movie. Which meant that the actors were cast for a variety of reasons, one of which was solid bank-ability at the box office. To those who complained that Eva Marie Saint is too old in this film, I'd like to remind them that she was only a few months older (in real life) than Paul Newman was. And having her a bit older than the character in the novel is fine, since she brings a different life perspective than someone in her 20s would have. Especially since she was playing a widow. just mho.
3. What has depressed me is that this IMDb discussion of a movie has brought out the Haters. I don't mean people who hated the movie; I mean people who hate Jews and the State of Israel. Apparently, no amount of art, or even actual history, will ever be enough for some people to stop hating, to get them to stop looking for every possible opportunity to malign any group of people they get something -- however perverse or destructive -- out of hating.
4. My personal opinion of this movie is that it's an excellent MOVIE. It entertains. It teaches us a few basic facts about the creation of Israel that most of us never learned in school. It is well-cast, well-acted, well-directed, and well-photographed. In addition, it has a great score throughout the film (not just the very memorable main theme.) I saw it at a movie theater when I was fairly young, and I've probably seen it on TV over a dozen times since then. I also read the novel (a long time ago), but if I've learned anything over the years, it's that movies and novels are different animals that can't fairly be compared page-for-page, so to speak. Heck - ever read "Gone With The Wind?" In the novel, Scarlett has one child with each of her husbands, but in the movie, she only has the one child, with Rhett. But no one complains about it because it's a damn good movie. And so is "Exodus." It's damn good movie.
