Once upon a time I attended a lecture about how there is a fine line between comedy and horror. Think about movies such as the Mummy and Frankenstein. Back in the day there was a comedian duo called Abbot and Costello. I saw their movies in syndication because I’m not THAT old and I know stuff that has happened before my glorious birth. They had a movie called “Abbot and Costello meet the Mummy”. They also had a movie called “Abbot and Costello meet Frankenstein.” The monsters both movies were basically the same. The same make up. I wouldn’t be surprised it the same actors played the monsters. The idea is you can make something scarey funny by tweaking the situation ever so slightly. It really isn’t surprising that lovers of comedy are also lover of horror. At a very basic level people recognize the similarities between comedy and horror. It is why we laugh when we find out the thing that just frightened us was only a piece of dust.
