I have never seen the play, but based on the movie I'm sure it is a deeply moving piece beautifully crafted for minimalist theater. A somewhat meta-King Lear, Anthony Hopkins and Ian McKellen are masterful and charming in this adaptation. However, all the trappings of a film feel unnecessary. There's something just a bit off about watching a movie both celebrating and mourning the desperation, obsession, and beauty of the theater. This movie was not at all bad, but it's something that needs you to emotionally connect and watching it on screen creates a degree of separation that hinders that connection. If The Dresser were to show up on stage I would see it in a heartbeat, but I can't say that it's something I would ever watch on film a second time.
