if you're interested in discovering Lynch but don't want to dive in head-first, try The Elephant Man (1980) and The Straight Story (1999). They're incredible, but very accessible too.
I thought, up until I read that post, that I had never seen a David Lynch film. But I have seen The Straight Story. From everything I have read about his movies, The Straight Story doesn't seem to be something he would do. Isn't it much more lighthearted with a simple storyline compared with his other work? It is a great movie though, I'll have to check out Elephant Man.
