Where do I start with Miklós Jancsó?

I'd say chronologically but check out The Red and the White and awe at his spacial awareness.
Cantata, My Way Home, Round-Up are great as well.

I once read that he was a big influence on Sergio Leone, is there any truth to that, or similarities even?

I kind can of see it, but they are very different, tonally I mean.
