10 Biggest Missed Opportunities In Horror Movie History
9. Guillermo del Toro's At the Mountains of Madness
This list could basically just be filled with unrealised Guillermo del Toro projects, the most promising of which was surely his intended adaptation of H.P. Lovecraft's sci-fi horror novella At the Mountains of Madness.
The Antarctica-set cosmic horror adaptation was first announced by del Toro in 2010, with James Cameron coming onboard to produce.
However, just three months later del Toro cast doubt on the ambitious project ever come to fruition, citing the studio's ambivalence at producing an R-rated period horror movie with a large budget, a bleak ending, and no romantic subplot.
By 2012, del Toro reiterated that the project was most likely dead, unaided by its similarity to the plot of Ridley Scott's Prometheus released that year.
In 2021 the filmmaker floated the prospect of tackling At the Mountains of Madness in stop-motion animation, though nothing more has come of it as of yet.
Del Toro did however release some never-before-seen VFX test footage in 2022, only further suggesting that the world was robbed of an incredible mega-budget Lovecraft adaptation.
