The bootlegs out there sourced from the TVland airings look really clean and good, except for the station watermark. THe ones taken from vhs mastertapes given to crew on the first batman movie in 1989 are uncut and have no station watermark but are shit quality.
All 16mm prints around are mostly very badly faded, at least the ones on eastman stock.
I wonder what shape existing 35mm prints are in if any exist, or the original negatives, ideally you want to work with the best film source for a restoration. With all the film grain intact, i noticed some of the new broadcasts seem to have boosted colors and look like video, film like DVD or Blu rays would be nice.
WB are cheapskates they won't restore the original superman film for Blu Ray so what hope is there for 60's Batman.
