I thought the story and movie were more the same than different. The people did have handicaps like the weights and earphones. Harrison was taken away just like in the story and was very handicapped in both versions of the story. Harrison had his dance with the ballerina too and the ballerina performance was live on TV and Harrison was also killed when he was dancing from the shotgun of the handicapper general.
Some differences in the story and movie were that Harrison never threatened the people in the theater that he had a bomb underneath the theater like in the movie. But, what he really had was a device that turned back on the TV signal so George could see Harrison dance. When I imagined the masks on the ballerinas, I thought the masks were going to be of ugly faces instead of the "mascaraed " masks people would wear at balls in the olden days. In the movie George was the one that cried when Harrison was shot, not Hazel. Finally, Harrison and the ballerina never kissed the ceiling. But,I thought both versions were great.
