Books to Movies: Richard Matheson's Hell House/The Legend of Hell House?

I haven't read the Richard Matheson book 'Hell House' nor seen the 1973 movie which was made from the book, but I have listened to a few podcasts about the differences between the book and the movie, much like I did when I wrote about Richard Matheson's book 'What Dreams May Come' -

What I find interesting about Matheson writing 'Hell House' was that in a 2011 interview Richard said every novel he has written was usually modeled off the house that he was living in at the time, all except 'Hell House' where he modeled the house in that story off the Hearst mansion.

I also found it interesting when I watched the movie 'The Life After Death Project' produced by Whitley Strieber's late wife Anne and featuring an interview with Richard Matheson, that Whitley also mentions his book 'Communion'.

The sequel to that book was read in an audio book version by Roddy McDowall, who also starred in 'The Legend of Hell House':-)
