@everetra - I’ve never read Of Mice and Men. Strangely enough, I’m aware of it, because the novel has been invoked in common slang as kind of a metaphor, like where you say if someone is a mouse or a man.
Regardless I think it would be worth a read. I’d be more interested in the novella though and not its adaptation to the big movie screen. I say that because in general, movies don’t always work well when adapted from novels.
At least this has been my experience, and I think that it would be even more so with the play novella.
