Chuck has the right answer. I used to be in this business. When we subtitled "Z," there was a long sequence where Yves Montand is in the hospital, dying, and everything is white -- the walls, the cabinets, the doctor's smocks. The subtitles were white on white, and unreadable. I asked if they couldn't make the titles black, just for those scenes, and was told it would have been expensive, and there was no budget for it. These days, they make a lot of subtitles yellow. The best subtitling job I ever saw was done by my brother Jon, for a film called "The Mother and the Whore" -- a terrific movie, mostly forgotten today, because its director, Jean Eustache, committed suicide at a young age, and didn't build up a body of work. "The Mother and the Whore" was a subtitlists nightmare, because it was immensely long, and all talk, talk, talk. There's one scene in which Jean-Pierre Leaud is sitting in a cafe, talking nonstop, and suddenly he launches a fusillade of untranslatable French puns. Jon agonized over this for a while, and eventually realized that the point of the scene wasn't so much what he was saying, but that he couldn't shut up. So his subtitle read: Here follow a series of untranslatable French puns.
