The score compliments the action nicely, but the colorization messes with the depth of the picture. Distracting during an age when black & white was becoming more crisp and defined, I wish I could have experienced this story in that style.
Cooper reneged on fidelity to his wife during filming, taking up a multi-film affair with Bergman, and their forbidden chemistry certainly does sizzle. In fact, it keeps the pace from languishing. The film, like Hemingway's novel, doesn't take time to educate you on the happenings of the Spanish Civil War; it assumes you know.
So considering the overt lack of political exposition, the nearly 3-hr runtime is practically inexcusable. The acting, the dialogue, is all Grade-A stuff, but it just takes too long. to. do. anything. That makes it hard to recommend, much less ever watch again.
Part of my Oscar Best Picture nominee journey, film #479/554.
