The DVD screeners had the same colour timing as the official DVD and Blu-ray.

Actually, no, this one doesn't look to. This is a screener made in August 2008, long before any official video transfer. Either way, there are lots of parts in the DVD screener that remind me of what I saw on the IMAX print (though the blues sometimes go too blue when they looked more cyan on the IMAX). And as I said, my memories of the 35mm prints line up with the IMAX (though my memory could be unreliable).

Yesterday, I was able to get a full-size IMG of the screener off Usenet, and I got a German camrip off Usenet too. (These took a lot of trial and error, many of the NZBs were missing parts or were outside my newsreader's retention period.) I think both versions could be of use.
