In the Star Wars: The Annotated Screenplays book The Empire Strikes Back director, Irvin Kershner, says of the torture scene:
I originally filmed more shots of Solo as he is being tortured. There were flashes of electricity everywhere. But it was cut out because we were afraid it might be too intense for children. We also took out some of his screaming offscreen when Vader is talking to Lando outside the cell.
