Most people probably are not familiar with his entire acting career, but horror fans knew Baledon very, very well.
He acted in hundreds of films but his most memorable, at least in my opinion was in the 1972 shocker "Asylum" where he portrayed Max the orderly in an insane asylum. His laugh still echoes with me to this day as he strangles and kills a visiting doctor.
Other genre films Baledon acted in where "Horror Of Dracula", "Tales From The Crypt", and "House That Dripped Blood".
In any film he was in, you never forgot the character he played. He died in England at the age of 93.
