There is one other film I know of which is based on Lovecrafts "The Case of Charles Dexter Ward", and that is the old Roger Corman movie "Edgar Allen Poe's The Haunted Palace", with Vincent Price as Joseph Curwen and Charles Ward. But The Resurrected is by far the most accurate movie about this story, which is damning it with faint praise.
The Resurrected is set in the modern day and Charles Ward is the head chemist at Belmar Cosmetics. He's rich. He has a beautiful wife. He's Chris Sarandon. But his wife detects that Charles is having some problems and so enlists a detective from the Marsh Agency to investiate. If you like the Call of Cthulhu game as well as Lovecraft you'll recognise how this movie goes: the detective makes his Library Use roll, uses his paid source to get info, makes an initial foray into enemy territory, then eventually finds the deepest secrets of Charles Dexter Ward. Almost everything in the book is in the movie: the painting, the formula for re-animation, the essential saltes, the pits, the initial destruction of Curwen in Revolutionary War times. It's all here and with good acting, costuming, and set. Curwens secret abode is everything you'd expect after reading the book.
Simply put this movie is great. It and maybe one other movie are the reason I still have a Laserdisk player, as it's sadly not yet out on DVD.
