Garth Marenghi wrote a novel that was given a film adaptation. This film is known as Troll 2.
The Darkplace UniverseThe literary universe created by Garth also contains the shows Look Around You and Time Trumpet. Lousy science facts and poor predictions, both caused by research Garth failed to did get because he pays people to get information he needs but was too tight to do so, instead he makes it up, with all the So Bad, It's Good consequences.
Garth Marenghi felt threatened by Todd Rivers / Dr. Sanchez...Dr. Sanchez is supposed to be the most notorious womanizer in Darkplace. But, that might imply that Dagless/Marenghi is less handsome and sexually desirable than Rivers/Sanchez. And since 'Dark Place' consists of all of Marenghi's ideas and fantasies, Marenghi had Sanchez castrated in the last episode so he wouldn't feel threatened anymore.
Sanchez is from Argentina.One of the documentaries on the DVD has Todd Rivers state that Sanchez fought in The Falklands War. He didn't say on which side Sanch fought, but Lucien Sanchez isn't exactly an English name.
