If you’ve seen one blockbuster, you’ve seen them all. So why not mix up your movie-going experience with a few classic Warner Bros. films at The Louisville Palace. Last weekend, the Palace showed “Casablanca” and “The Maltese Falcon.” This time, it’s “Yankee Doodle Dandy” on Friday and “The Adventures of Robin Hood” on Saturday. If you can’t catch those, the following weekend is “Citizen Kane” and “White Heat.”
