Editing House of Leaves (section)

==Companion works==
{{original research section|date=July 2023}}
The book was followed by a companion piece called ''[[The Whalestoe Letters]]'', a series of letters written to the character Johnny Truant by his mother while she was confined in a [[mental institution]]. Some (but not all) of the letters are included in the second edition.

''House of Leaves'' was accompanied by a companion piece (or vice versa), a full-length [[album]] called ''[[Haunted (Poe album)|Haunted]]'' recorded by Danielewski's sister, [[Poe (singer)|Anne Danielewski]], known professionally as Poe. The two works cross-pollinated heavily over the course of their creations, each inspiring the other in various ways. Poe's statement on the connection between the two works is that they are [[parallax]] views of the same story. ''House of Leaves'' refers to Poe and her songs several times, not only limited to her album ''Haunted'', but ''[[Hello (Poe album)|Hello]]'' as well. One example occurs when the character Karen Green is interviewing various academics on their interpretations of the short film "Exploration #4"; she consults a "Poet," but there is a space between the "Poe" and the "t," suggesting that Poe at one point commented on the book. It may also be a reference to [[Edgar Allan Poe]].

The album ''Haunted'' also draws heavily from the novel, featuring tracks called "House of Leaves", "Exploration B" and "5&½ Minute Hallway", and many less obvious references. The video for "[[Hey Pretty]]" also features Mark Danielewski reading from ''House of Leaves'' (pp.&nbsp;88–89), and in ''House of Leaves'', the band Liberty Bell's lyrics were also songs on Poe's album.

In 2017, Danielewski entered talks to adapt the novel into a TV series,<ref>{{Cite news |last=Wampler |first=Scott |date=July 9, 2018 |title=Mark Z.

A sequel to the book, the screenplays both adapt the original story and extend it to the present day. Past sequences, depicted as filmed by a then-young filmmaker named Mélisande Avignon, contradict the book significantly: Zampanò's work, found by Truant, was not a manuscript but the actual film footage of ''The Navidson Record''. This and Avignon's film are later seized, and public knowledge of them suppressed, by a "data disposal" company called Skiadyne. In the present, unknown forces steal both films from Skiadyne and return them to Avignon, leading to a high-stakes fight for control. The book ''House of Leaves'', now academically studied as a work of fiction, becomes embroiled in a "fake fiction" scandal when Avignon publicizes its factual basis by leaking the films.
