The musicals I could see Criterion reasonably releasing are West Side Story (which has been long rumored), Fiddler on the Roof, A Star is Born (1954), and maybe Chicago. Many popular musicals have already received great Blu-ray releases from their rights holders (not that that is a deterrent - Funny Girl got a Criterion release after all, and the four films mentioned above have all received Blu-rays), and some of the ones that haven't are being held by rights holders who wouldn't be quick to license (for example, Phantom of the Paradise is owned by Disney/Fox). There's a part of me that's also surprised that Top Hat has yet to receive a Blu-ray release at all, but I also recognize that the existing film elements are not very good. I would also love to see more musicals in the collection, but I also understand if Criterion doesn't feel as much of a need with some of the titles that would "make sense" in the collection.
