Trivia: A great deal of Flint Marko/Sandman's storyline was edited out of the film by the studio due to the long run-time. One scene early in the film showed that the scientists who accidentally created Sandman were racked with guilt when they discovered they might have activated the machine with a person inside of it. Another scene had Sandman visiting a doctor researching his daughter's rare disease whom he had been corresponding with in prison. Yet another scene showed him following his daughter in a park, and morphing into a giant sandcastle that she plays with. And finally, his daughter was going to appear in the final battle, and would appeal to her father to stop hurting people and living a life of crime to get money, as she accepted that she was going to die no matter what. Her words would be what convinced him to seek forgiveness from Peter for accidentally killing Uncle Ben.
