Alarma en California

My name is Billy Walker and my father was a set designer for this film. I saw the film in Dallas Texas in 1958 shortly after my fathers funeral. AS a boy of eleven years I was totally consumed watching this movie. I had a black lab puppy at the time and this film opened a fascinating door for the imagination. I had not seen my father for three years, with the exception of at his funeral service as he had been in the L.A. area working on various movie sets. I am hoping that some one can steer me in the right direction to obtain a copy of this film. My father was the man sitting at a corner coffee stand who shared his food with London. Help in this endeavor,from anyone, will be greatly appreciated.

Thank you, Billy
