The poster of The Thing stands guard over Mike’s basement, the sanctuary of Stranger Things. As the very first film to appear in the series, it is the show’s DNA personified. It serves as a grim foreshadowing of the Mind Flayer, which invades by seizing the minds of peaceful townsfolk, and was a pivotal influence in bringing the Demogorgon to life through special effects. This is the Duffer Brothers’ ultimate favorite film, to which they pay profound tribute and respect. From Mr. Clarke’s date night featuring the grotesque melting head to Lucas comparing 'New Coke' to the film—claiming it’s 'sweeter, bolder, and better'—the two clearly share the title for the world's strongest stomachs.
