“Well, you should not make that change, and this is an interesting question. Because if something is framed properly, shot properly within the 4:3 format, then you should leave it. You can put it out on Blu-ray, but leave it as it is, with the black pillars on left and right. I would definitely do that with Portishead, and The White Stripes. With the latter, it’s critical that it stays on 4:3 because it was shot on Super-8, and it’s got that bootleg feel about it.”
