I don't know anyone who is blind and I have never interacted with blind people. Edward Hogg was a very convincing blind person (as far as my limited knowledge of blindness goes). Great actor with a lot of charisma. "They look but they don't see" - yes, that should be written on the foreheads of most of us who aren't blind. I think I will appreciate the sounds and scents of life a little bit more from now on after seeing this excellent film - a subject not many have covered in show business. What I would want to know though, is it possible for a blind person to fine tune their other senses so much that they don't need a cane or a dog?
