Working on one of these now, and I've turned to "Amadeus" and "Little Big Man" and "Chariots of Fire" -- as well as the more current films above -- for guidance. A protagonist with memory loss in the present is a very common and useful trope for going back and stitching non-linear moments into a good mystery or thriller. And of course there is always Clarence's Call to Adventure by the VO galaxies in "It's A Wonderful Life"...
