Some movie-franchises are so popular, that they were continued for two or more decades. The ideas of these movie-franchises are so unique and/or popular that fans crave new movie-releases. Mostly they have fans over two or more generations. What is your pick from the franchises below? Only big money movie franchises lasting more than 2 decades with a worldwide boxoffice (all-in-all) above 300 million dollars. Feel free to contribute or discuss. Special thank you to all contributers. Thanks to my wife for this special idea, Dan Dassow, Jessica, rubyfruit76 and Ibrahim Akhtar for contributing.
