Hi Zach, I'm not that much fan of Lynch but I agree both films could fit here and they're indeed relevant in recent movie history. So, putting personal tastes aside and going for objectiveness I think I'll include them.
Oh what a great list! I love movies about making movies! In many ways, both Mulholland Dr. and Inland Empire could be on that list.
But, they're very different from these, I guess.
