WC - Something like 90% of movies are adapted from novels. Some of the most important films ever made were adaptations: Gone With the Wind, The Wizard of Oz, Dr. No, and Jurassic Park (yes, it’s important) were all adapted from popular novels. In turn, many of the lamest video games are adapted from those movie adaptations: E.T. and Independence Day to name two of the most egregious examples. Oh, and–if you want your mind melted–there’s always the 1995 fighting game based on Street Fighter: The Movie which technically makes Christopher Nolan 15 years late to the Inception concept.
