Did You Know?


The documentary The Man Who Saw Frankenstein Cry (2010) got the title due to an anecdote that happened in this shooting. Here's the text that was shown at the end of the documentary: "At the end of the 60s, the I Spy (1965) TV show crew arrived to Spain in order to film some episodes; in one of the Boris Karloff had a role. Among the extras that they had looked for this episode, they found a young man who was hiding that he was trying to get on in cinema from his parents. His name was Jacinto Molina (Paul Naschy). At the end of the working day, Karloff was waiting for the car that would take him to his hotel. He did so for hours while cold and night were adhering to him. While Jacinto was looking from the distance, some tears appeared on the actor's old face. Nobody else was witnessing that moment. That day, Jacinto became the man who Saw frankenstein cry."

Karloff Shines with Enthusiasm
15 May 2012 | by (United States) – See all my reviews

As a Boris Karloff fanatic , I had to track down this episode. I had seen it as a child on it's original run , and always remembered the scenes of Boris fighting the windmills, a la Don Q. Boris is a nuclear scientist who has developed anti-missile technology. Of course, it's up to Culp and Cosby to convince the nutty Boris that the good old USA will use his discovery for the good of humanity. In the meantime , Karloff leads our heroes into some bizarre situations that are life threatening including deadly encounters with some nasty German agents who also want the technology for their own evil purposes. Boris is surprisingly athletic here, considering that he had just filmed "Die , Monster, Die" , playing the entire movie from a wheelchair. Here, he runs (albeit with an obvious leg brace), is flipped up in the air by Spanish peasants, and wonders about energetically, giving a wonderful performance as an old man with Alzheimers. This episode really shines compared with some of the other TV work he was doing at the time (The Girl from UNCLE , The Wild Wild West). Karloff fans will want to see this one.
