Lon Chaney could wear the harness for only ten minutes before the pain became intolerable.
Lon Chaney had both of his lower legs tied back and had to walk on his kneecaps for his role as an amputee. It was so painful he could only have his legs tied back for a few minutes at a time, and his leg muscles sustained permanent damage.
A shot of Lon Chaney walking down stairs was put onto the end to prove the audience that he was not an amputee. It was removed from the 1926 release and the film footage is now lost.
Lichtenstein can clearly be seen mouthing the word "Damn!"
