Halloween may be over, but try telling that to horror legend William Castle. The man won’t even acknowledge the fact that he’s been dead for over 30 years. As those who knew him best will say, Castle does what Castle likes … and what Castle likes most is terrifying the pants off people.

That’s why the infamous producer of Rosemary’s Baby has released “House on Haunted Hill: A William Castle Annotated Screamplay,” a 248-page book featuring the working script from his 1959 classic horror show House on Haunted Hill, complete with his very own hand-written notes and original formatting. An introduction from renowned producer/director Joe Dante (The Howling, Gremlins) is also included.

“House on Haunted Hill: A William Castle Annotated Screamplay” is now available at Amazon and selected retailers (visit the William Castle website for more info). But, those living in Los Angeles can pick up a copy autographed by Castle’s daughter Terry at Larry Edmunds Bookshop on Thursday, Nov. 10 at 7:30pm.

Those attending the event will be treated to trailers, clips and secret surprises … who knows, maybe, even a William Castle ghost sighting.

Castle returned from the dead last May during the 33rd anniversary of his death and has since published the young-adult novel “From the Grave: The Prayer” and set up Twitter and Facebook accounts to stay in touch with fans.
