... that being Erich Von Stroheim and Dwight Frye. Von Stroheim plays Dr. Crespi, the chief surgeon at a hospital. Early scenes show him being dictatorial, like most of the parts he played. He bullies Dr. Thomas (Dwight Frye) when he doesn't know the exact time of death of a patient.
A woman that he loved who married somebody who was once Crespi's friend comes to Crespi and asks him to operate on her husband who has been in an accident and needs a skilled surgeon. Crespi agrees, but instead he has a hideous fate planned for the man that he feels stole the girl he loved and has had a more prominent career than Crespi.
Crespi discounts Frye's character as somebody he can bully into submission and keep quiet about what he has done, but he has perhaps watched Dracula and Frankenstein one time too many, for Frye is not playing the fool in this one. I think this is the only film I have seen - there may be others - where Frye plays a normal person, albeit in an abnormal situation.
The one thing that is done that almost seems like filler material is the insertion of a troubled romance between a random doctor and a nurse. It's the only real negative in the film as it just bogs the proceedings down with a situation that isn't even interesting.
The art design is very good for a poverty row product, with some kind of strange half skeleton half alien knickknack adorning Crespi's office. Maybe Erich Von Stroheim was a visitor from outer space all along? That would explain a lot!
