I remain firm in my opinion that the appearance of "237" in films is because directors - after The Shining (1980) - are placing the number in their films as homage to Kubrick.

Directed by John Carpenter, he inserted the license plate "PXV 237" in the script for the vehicle (a red Mustang) used by the alien and his companion.

This film is not mentioned in the Crypto-K video series but has been noted in @Cryptokubrology tweets. Capote is a 2005 biographical film about Truman Capote directed by Bennett Miller. Capote was played by Philip Seymour Hoffman (born July 23, 1967 – died February 2, 2014). In Capote, Truman (in the phonebooth and talking to his lover Jack) visually flirts with a man for an implied sexual interlude as he is waiting outside the bar under the numbers 237.

The 237 number in the screen name is a reference to director Lee Unkrich’s favorite movie The Shining.
