Tarantino & Nolan already got shouts in the thread, so:

John Carpenter for some of the best practical effects in cinema history

You’ve also got the likes of Stanley Kubrick & David Lynch, of course

I feel like you could go on a great journey through 80s-00s cinema with films having either Bill Murray or Arnold Schwarzenegger in the cast

There’s probably a lot I’m forgetting
