This is the complete list according to Wikipedia, listed by spine number. I will make notes on the ones that are currently out of print.
I'm also including titles from Criterion's Eclipse imprint, for completist's sake.
Now, of course, I've already seen a bunch of these, but I'm going to try to watch them all again (along with the ones that I haven't seen) to fill in any gaps that I might have, esp. in World Cinema.
It's a process.
