I have seen 704 of the 1001 Movies You Must See Before You Die. My goal is to see all of them, but that may be impossible, since there are about 75 titles on the list which are either out of print, never released to home video, or never released to theatres.
When I started my quest, in May 2004, I had seen about 200. Of the 504 I've seen since then, 340 came from Netflix. I now have 219 movies in my Netflix queue, all of which are on the list of 1001. Eight of them are in the saved section, because they are "release date unknown."
I am using the 2002 edition of the book, which is out of print, but you can buy it used, or find the 2004 edition, which has a few different titles on the list.
You can see the list of Films I've Seen of the 1001 Movies You Must See Before You Die on Listology.
The last time I posted a milestone from this book was October 13, so it has taken me four months to see 100 films on the list.
