My guess is that with Apple giving it a limited theatrical release at some point a disc will come out. MY thinking (and I'm saying this as a consumer, not an Apple exec) is a physical release will get MORE viewers which in turn could help generate more Apple+ subscribers. Heck...
Fantastic film. I really want to track down the original. I have never liked Joni Mitchell's "Both Sides Now."
Until this film. As someone stated, there aren't any surprises in the story, but the cast is excellent and it is definitely worth seeing.
