I watched The Hateful Eight for the first time recently. Due to how dialogue heavy it is, I was thinking it'd probably work as a radio drama. It's not just that it's dialogue heavy though. The great cast made the dialogue feel important, even when it really wasn't. That or something similar in terms of dialogue and casting would probably be a good choice. A strong soundtrack would be important too, which The Hateful Eight also has. I'm not sure it'd actually be the movie I'd choose, but it'd definitely be one to consider.
