He is said to haunt his former home which he shared with Anne Baxter. A resident who lived in the house during the 1970’s, and knew John Hodiak quite well, had many experiences which was put down to the actor, including a telephone call which manged to whisper hello. A guest at the house saw a figure outside a second-story window evidently floating in the air. She later identified the ghost as being Hodiak after seeing one of his films.
