That would really be amazing. At the Mountains of Madness is one of Lovecraft's best stories, I think. Seems as well. Would be nice to see how tall they can make those mountains. I definitely have difficulty imagining the size described...
By chance, I got the Accessory Pack for the Call of Cthulhu adventure some time back in an old-stuff-box at a game fair, not even knowing what it was but thinking "hey, this looks cool". As I had it lying next to me, somebody tried to snatch it away, actually. Should have been my first clue... Then I found out how rare that is and spent about 5 years hunting for an affordable version of the adventure. First, I only found them for, like, 200 $ upwards, and only from US dealers, then an auction in Europe went past 90 € (what I was willing to pay at that time, that wonderful time when I was working, not studying, and still had money *sigh*). About a year ago, I finally got one via eBay.
From Sweden.
Now I'm trying to find the time and people to play that in the manner it deserves.
As for Lovecraftian movies, apart from "errr... not quite"-kinda , more or less loosely based on Lovecraft's work there is actually one really good one: released a modern black-and-white silent movie for which I find simply amazing. They even have convincing non-Euclidean geometry!!
They are now working on a black-and-white non-silent adaption of .
I just love their style of filming, fits Lovecraft sooo well.
Oh, John Carpenter's with Sam Neill is actually quite good, too, I think.
