20 Behind-the-Scenes Secrets From Stranger Things
A real guy played the Demogorgon at one point.
Many people probably assume that the Demogorgon on Stranger Things is thanks to CGI. That is not completely the case. The character was played by a real actor. Mark Steger is credited as playing “The Monster” on Stranger Things on six episodes of the show during the first season. (One appearance from season two is uncredited.) It is thought that 50 percent of the demogorgon is “practical” and the other half is special effects, but the show execs were originally hoping for a 80-20 split. Mark has a history of playing creepy characters in Men in Black II and on Heroes and American Horror Story.
