Many cinemas actually use BDs for showing older movies.
That was not the case, as there were exploitation visa numbers for each one that don't appear in the Blu-ray subtitles. But I do suspect that's what they did in another theater I went some months ago to see Forrest Gump: the subtitles were so badly done and had the same font as on the Blu-ray. What a pity! And the whole thing lacked some definition.
