The musical has become one of the staples of modern Hollywood. Studios have made a tradition of taking a recognized Broadway show and adapting it into a lavish film. Sometimes the musicals are disasters, like Rob Marshall's "Nine," which had Daniel Day-Lewis, Marion Cotillard, Penelope Cruz, Judi Dench, Sophia Loren and Nicole Kidman -- but was completely incoherent. And sometimes the musicals have great music and great casts but just do not translate into great films. With the release of Clint Eastwood's "Jersey Boys" and Marshall's soon-to-be-released "Into the Woods," here are some of my favorite musicals.
