Author Comments: 

I took some license with the definition of a trilogy. For example, there were many more Dr. Mabuse films but I only count the ones made by Fritz Lang. A couple of others were written as trilogies, but made by different directors.

I'm probably forgetting a couple and I haven't yet seen Kobayashi's Human Condition trilogy.

I haven't seen 2046 yet (seeing it tomorrow probably), but it forms something of a loose trilogy, so I'm told, with Days of Being Wild and In The Mood For Love.

Also, re: the "California Trilogy" - I mean I kind of get it, they're three major 40s film noirs based on James M. Cain novels, but, I guess it just seems odd to me seeing as they're all made by different directors

Yeah, I did say I had a couple that were written as trilogies but by different directors. I was also going to list the original Star Wars trilogy but I bumped it in favor of Qatsi.
