These days, it seems movies based on IP are inescapable. From the endless string of superhero films to reboots and remakes, and even films based on theme park attractions, it seems that the age of the franchise will be here to stay for some time. Interestingly, though, movies based on popular video games have often yielded mixed results. There are occasional successes, such as The Super Mario Bros. Movie, but there are plenty of disastrous flops, such as Borderlands. This hasn’t stopped Hollywood from trying to make a video game-based franchise work, however, as evidenced by the upcoming Minecraft movie. Warner Brothers and Legendary Pictures are certainly going all in on the movie, and given the game’s immense popularity, the film could indeed become a massive hit. But there’s one game-based picture we never got to see, one that could have truly revolutionized the subgenre: RollerCoaster Tycoon. One of the most popular franchises of its day, the movie was in development and was set to take the popular simulation game in a fascinating new direction before being mysteriously canceled.
