At the Mountains of Madness may make it to the screen after all, though whether little or big is anybody’s guess.
In an Indiewire interview Guillermo del Toro talks about his upcoming Pinocchio on Netflix and how animation (of the stop motion variety) inspired his work in live action.
Pinocchio was Guillermo del Toro’s stop motion debut though that was more due more to circumstance of the cruelest sort than his intent because over three decades ago the auteur was preparing his first feature film, Omnivore, which would have been entirely stop motion though a few days into production his studio was vandalized and the models destroyed, which lead to him working in live action with Chronos (1993).
And while I enjoy stop motion as well and could see it working, what I’m not sure of is if Lovecraft’s story of a doomed Arctic expedition wouldn’t be better served by live action (if you’re wondering what it would look like, take a look at Hellboy (2004), which is very Lovecraft-esque at points though I’m specifically referring to when Kroenen and Ilsa head to the Arctic wastes to revive Rasputin).
Or at the very least, something like the work of Ray Harryhausen (Mysterious Island, The Golden Voyage of Sinbad, Sinbad and the Eye of the Tiger, etc), which are a marriage of live action and stop motion animation.
