I want to inject some personal information that I learned after my original 2002 review of same. I made contact with Johnny Duncan who starred as Harold Morgan in the movie. We connected thru his fan club and I conversed with him about the film and Helen Parrish, the star. We exchanged emails initially and then he gave me his phone number so we could talk in person. He was at that time the only living actor of the film. We reminisced about the actual making of the film and his interactions with William Beaudine and Helen Parrish. He confirmed Helen was as beautiful in person as she appeared on screen. The had lunch every day at the Monogram lunch room and he said they even ate with Bela Lugosi! He had on his makeup described as a greenish grease paint as he was also in a horror film at that time. He described Beaudine as man in motion, constantly making last minute changes to the scrip and never call "cut" unless the camera film broke! He remembered the movie took about 6 days to complete and then they had a party with all the actors and stage hands. I also told Duncan I had 16mm prints of 13th Guest, Batman and Robin serial and Delinquent Daughters, three of his best films in my opinion. He also invited me to come and see him in the Ozark's in Mo. He sent me an autographed picture of himself in costume as Robin in color. At that time he was still active and even as he said, mowing his lawn in his 80's. I never made it down there and found out he passed last year at 89. In my original review of 2002, I mentioned Dick Purcell, playing Johnny Smith was a reporter, He was actually a PI (private investigator). He died in 1944 (39 yrs old) after playing 18 holes on a Beverly Hills Golf Course. In closing for anyone interested in conversing further about The Mystery of the 13th Guest film or the actors especially Helen Parish or Johnny Duncan, feel free to contact me thru Facebook or the review.
