As we all know many people tried to make a Lovecraft movie and most failed. Personally i am remaining hopeful that one will eventually be made witch will be good, or at least they could make a decent HBO series...
But from the old movies so far all that i have seen are Call Of Cthulhu and Dagon. Call of Cthulhu considering its age is a decent movie and i enjoyed it a lot, while Dagon is basically The Shadow Over Innsmouth and to tell the truth not that well done. I haven't read the story yet but probably didn't spoil it to much ;).
Lovecraft's work has even reached out to comics, as of yet I haven't had the luck to get one :( but from what I heard from the LEOG there are some good ones out there.
Now we come to the final medium games. Yes even there we can see the Lovecraft's adaptions. One of the best ones being Call of Cthulhu: In The Dark Corners of the Earth. The game it self has some faults but when it comes to story and atmosphere its spot on. It's a must for any Lovecraft fan. Also I have noticed Lovecraft has been an inspiration for many of today's horror/thriller games. One of the most recent ones being Dead Space.
Also there are a lot of decent fan made videos dedicated to Lovecraft or varies story adaptions witch are really good and are a must to see.
If you have seen any of the other movies or comics etc... just post your opinions here.
Ok so far i have seen all the Re-animators first one was kinda good, but i would kinda combine 2 and 1 to get the real true to hart interpretation of the story. Good news on the comic side, a friend of mine bought me a pack of Lovecraft based comics so i can enjoy that :P Ill post witch ones I have later.
As for witch Lovecraft, im reading, its The Horror at Red Hook, so far its really interesting :P
In terms of games, there's a new one I would highly recommend.
It's called Cthulhu Returns, a downloadable MMORPG game (for free YAY!)
The game is still in BETA testing, probably will be for a long time since the creator is having trouble finding time to work on it.
That aside, it's definetly worth playing, you get to pick from 4 main classes (detective, scientist, mysic, cultist- though the last isn't out yet) and take part in missions drawn from Mythos of Lovecraft, one mission has you searching for the missing Dr. Herbert West, the search leads to his house where you must fight your way through a bunch of reanimated corpses. Like I said earlier, the game isn't finished and still has a lot of stuff to add to it, the creator has promised to, eventually, have players run across Pickman's Model, explore the mysterious town of Innsmouth, explore the Dreamlands, and more.
To any fan of Lovecraft's work I highly reccomend checking it out: http://www.cthulhureturns.com/
