Apparently there is a short film (50 minutes or so) made by the guy who did all of the HDTV sequences which apparently follows Wim Wenders around Tokyo. I have never seen it (it was included as side four of the japanese laser disc), but if you can track it down, it would probably be worth including as part of your special edition.

In other news related to this most neglected of films, the release date for the fabled UK version has come and gone without any evidence of an actual DVD. Boo.
