## In culture

### In film and television

237 is the number of a haunted room in the Overlook Hotel in the Stanley Kubrick's film The Shining, and part of a network of interrelated numbers within the film[4] (see The Shining (film)#Room number and the documentary Room 237).

237 is also the number displayed on the TV set in the 1982 film Poltergeist, when Carol Anne is attacked by the ghost, as Spielberg wanted to pay homage to The Shining. Steven Spielberg specifically requested this number to be displayed on the television in his production notes.
