As Above, So Below (film)

As Above, So Below (stylized as As Above/So Below) is a 2014 American horror film directed by John Erick Dowdle, who co-wrote the screenplay with his brother Drew Dowdle. It stars Perdita Weeks, Ben Feldman, Edwin Hodge, François Civil, Marion Lambert, and Ali Marhyar. The film is presented as found footage of a documentary crew's experience exploring 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 Dante's Inferno, and its title refers to the popular paraphrase found in the Emerald Tablet. It was the first film to be granted permission to shoot in the actual Catacombs of Paris. It was produced by Legendary Pictures and the Dowdle brothers' own company Brothers Dowdle, and distributed by Universal Pictures, making it the first film released under Legendary's deal with Universal.

The film was released theatrically on August 29, 2014. It received mostly negative reviews from critics but was a box office success, grossing $41.8 million worldwide on a $5–10 million budget. In September 2018, four years after its release, it became available to stream on Netflix; it became extremely popular on the platform, subsequently garnering a more positive reception and building a large cult following.
