Dave Stevens is dead, from cancer, at age 52. I know very little about his life and career, but I do he created the Rocketeer. This is a wonderful comic, set in the 1930s in Hollywood, and still easy to locate. It was also a movie from Disney that stands as one of the best comic-to-movie translations. Watch it again, there is fun and joy in that movie that a lot of comic book movies forget.
Sadly, the movie did not do well, and there is little lasting impact of it in the parks. When I first went to Epcot in 1995, there was an exhibit about a Blue Sky concept for a virtual reality attraction that never came to be.
