Here is one of my favorite interviews of them together on the Charlie Rose show Dec 20, 2006. I remember re-watching this video from my apartment in Memphis over and over again back in 2006.
Films: Babel, Children of Men, Pans Labyrinth

In addition, two of them won Best Picture too:

Birdman, Alejandro G. Iñárritu
