Coco co-director Lee Unkrich has been throwing references to The Shining into Pixar’s movies for years, and you bet he managed to squeeze a few into his latest.
Also I think it was because it was the first film I saw that so pervasively had a specific mood to it.
Though they’re not all explicitly connected, each movie contains references to previous Pixar movies for avid viewers to find.
Unkrich also said that the third reference has to do with the scary twin girls The Shining’s Danny meets in the hallway of the hotel.
