<Li> Director Guillermo del Toro and screenwriter Matthew Robbins wrote a screenplay based on Lovecraft's story in 2006, but had trouble getting Warner Bros. to finance the project . Del Toro wrote, "The studio is very nervous about the cost and it not having a love story or a happy ending, but it's impossible to do either in the Lovecraft universe ." In July 2010 it was announced that the film would be made in 3D and that James Cameron would become producer, and Tom Cruise was attached to star . This "was a startling prospect considering Lovecraft's tale had long been considered unfilmable ." Del Toro confirmed that the film would begin production as early as May 2011 and start filming in June . However, in March 2011, it was announced that "Universal Studios refused to greenlight the project due to del Toro's insistence that it be released with an R rating rather than a PG - 13 ." In 2012, del Toro posted that, due to the resemblance in premise with the Ridley Scott film Prometheus, the project would probably face a "long pause--if not demise". In 2013, del Toro stated in an interview that he would try one more time to get the picture made . </Li> <Ul> <Li> David A. McIntee noted similarities between the first half of the 1979 science fiction horror film Alien, particularly in early versions of the script, to At the Mountains of Madness, "not in storyline, but in dread - building mystery", and calls the finished film "the best Lovecraftian movie ever made, without being a Lovecraft adaptation", due to its similarities in tone and atmosphere to Lovecraft's works . In 2009, Alien writer Dan O'Bannon said the film was "strongly influenced, tone-wise, by Lovecraft, and one of the things it proved is that you can't adapt Lovecraft effectively without an extremely strong visual style...What you need is a cinematic equivalent of Lovecraft's prose ." </Li> <Li> Prisoner of Ice is a 1995 adventure video game by Infogrames that tells a story set in the aftermath of the expedition . </Li> <Li> "A Colder War" is a loose sequel to At the Mountains of Madness written by Charles Stross in 1997, where the secrets from beyond the Mountains of Madness are used by the Cold War superpowers to dreadful effect . </Li> <Li> Chaosium Games released a campaign book titled Beyond the Mountains of Madness for their Call of Cthulhu role - playing game in 1999 .

It featured a Miskatonic University archaeologist named Robert Naples attempting to stop the Nazi occult search for the Elder City . </Li> <Li> In 2005, Elder Signs Press published Hive by Tim Curran . In the story, set in the present, the Plateau of Leng has crumbled under the ice and snow due to geological changes, the Shoggoths are non-existent (with Dyer's accounts of them overthrowing the Elder Things having been chalked up to stress and madness), and the Elder Things, both living and ethereal, still exist under the Antarctic ice . The plot deals with a group of American explorers unearthing an Elder Things' tomb and citadel . A parallel plot also deals with an expedition using an experimental submersible to breach Lake Vostok, which is named as the location of the underwater city to which the Elder Things fled . </Li> <Li> In 2009, Atlas Games published The Antarctic Express by Kenneth Hite and Christina Rodriguez, part of the Mini-Mythos line of books from Atlas Games (ISBN 1589781112).
