Wanted to jump into doing lists for the showdowns and this seemed like a good a place as any to start doing them.

This isn't a ranked list in any sort of way, just listed in the order they came to mind. I think most of them speak for themselves as to why they're on the list. Either they demonstrated mind blowing visual effects obviously, or in the case of Brokeback Mountain, so subtlety you'd be shocked at how much visual effect work went into that film.

I think they're all worth a watch, just to witness the sheer amount of work that went into them on the visual effect side of things.
