Watch The Shadow Glass (1976) Official Trailer

The Shadow Glass is roughly based on Ewers' 'Student of Prague'. It concerns a young man who, feeling incapable of surmounting the harsh realities of love and life, sends his reflection cut to procure and win for him the object of his desire. Rather than being his servant and slave, the reflection takes over and controls the life of the man. In frustration and anger the man kills his reflection in order to be set free. The reality of the situation is the reality of suicide. The entire film could be interpreted as taking place in a brief second–for as long as it takes pull the trigger.
