I was having lunch with Tony Cervone, the Animation Director of SPACE JAM, and complimented him on what a brilliant job he had done, especially in designing the MONSTARS, that were based on real players, Charles Barkley and others, and remarked how the notion of parallel universes existing in the film (and the commercials the film was based on) were never discussed. A few days later, this brilliant essay showed up, and may have been a sore subject with Tony for some time.
