What is his best film?
I haven't seen all of his films, but I think his best film is Gravity.
shareChildren of Men
shareChildren of Men by far.
shareI also say "Children of Men"
shareI'm going to fly the flag for Y Tu mama Tambien, that film deserves a lot more love. Great film, plus Maribel Verdu as one of most underrated beauties, damn she's smoking. Bernal and Luna have great chemistry together.
But Children of Men is a classic. Still think Gravity is overrated, probably that's just me.
Y Tu Mamá También followed by A Little Princess.
shareI really liked Roma, but I have yet to see Children of Men. I liked Gravity too.

Roma
Y Tu Mama Tambien
I began a fan of his two decades ago, my answer is alwasy the same in 20 years: A Little Princess.
It's his first movie, and still the best movie.
