I suspect there's still some resistance from the Beatles or their heirs for these programs not to be released. Am I wrong? Can Apple release them anyway without Beatle consent?
MMT they might be able to, since it's an Apple film. But Let It Be
is a United Artists movie, I believe, so I would imagine it's up to UA to decide if it should come out.
Personally, I don't think either one will ever be released legitimately, or if they are it won't be for a long time. Neither film plays to the Beatle "myth" of happy go-lucky mop tops; Let It Be
is so depressing (except for the rooftop concert); it basically shows four guys who are tired and don't want to be together anymore. In of itself that doesn't make for a bad movie, but combine that with poor sound, grainy film and questionable editing and you've pretty much punctured the Fab Four myth that Capitol/Apple loves to push.
As for MMT, well, there's another thread on whether that's good or bad (I am definitely of the latter opinion!) but I can't see Macca or Ringo saying "Sure, let it out."
