As Above, So Below is a 2014 American horror film directed by John Erick Dowdle, who co-wrote it with his brother Drew Dowdle. It stars Perdita Weeks, Ben Feldman, Edwin Hodge, François Civil, Marion Lambert and Ali Marhyar. Presented as found footage, the film follows a group of explorers venturing into the Catacombs of Paris in search of the philosopher's stone, only to be confronted by supernatural forces. The film is loosely based on the nine circles of Hell from Inferno, the first part of Dante Alighieri's Divine Comedy, and takes its title from the Hermetic maxim "as above, so below", a paraphrase associated with the Emerald Tablet.
