Interesting doc about a Warner Bros production which has Tim Burton as director, Nic Cage as Superman, and a bevy of screenwriters, animators, costume designers, special effects geniuses, and conceptional artists which goes through numerous changes and developmental problems before the studio pulls the plug after a series of box office bombs during a disastrous stretch. You get to see Cage in costume tests, with doc director Schnepp interviewing Burton who is thankfully candid. Those brilliant artists involved and their work are given some well deserved notice as are the funny comments on interviewee producer Jon Peters regarding his eccentricities and how those working on the film were annoyed by him. Kevin Smith had an early script ultimately denied and Peters conflicts with him regarding what they were aiming for in developing the film. A Superman film was made but what you see of what might have been could have looked visually amazing. Peters and his spider, Smith and his profane reflections, artists reminiscing about the production, debate over how to make Superman a bit different than previous incarnations, updating the origin of Superman, how Burton and Cage were intrigued with putting a unique spin on the character, creatures involved with Superman and his home world, and other casting possibilities like Walken as a villain named Brainiac are memorable highlights.
