I fell like Snow Crash would be much more successful as an animated movie. There's a lot of whimsical, somewhat silly stuff in there that works in a book and could work animated but doesn't translate well to live action.
Once you try to make it "gritty" and "real" you end up with clunkers like Hackers or Johnny Mnemonic. I guess you could point out stuff like the Matrix or the recent Batman franchise, but those tend to be the exception not the rule, and to be frank, cater to an almost goth-level of drama and pathos.
