La dernière demeure des Hill.

Robert Kurtzman reveals that up to 30 "Easter egg" ghosts are planted throughout the series. "It was [creator/director Mike Flanagan's] plan from the beginning to set up these kinds of little Easter eggs and see if people could spot them." While working on the primary prosthetic makeup for the show each day, the makeup team would also produce up to four of the "hidden ghosts" as well for Flanagan to pepper in the shadows.

Even though Hugh's right hand is severely injured by a fan while staying at Hill House, there is no visible scar on Adult Hugh's hand.

The DVD and Blu-ray releases feature extended and/or previously unseen scenes in episodes 1 (Steven Sees a Ghost (2018)), 5 (The Bent-Neck Lady (2018)), and 10 (Silence Lay Steadily (2018)). The added material totals approximately: 5 minutes in episode 1; 3 minutes in episode 5; and 4 minutes in episode 10.
