It may surprise some people to learn that there are six million people buried under the streets of Paris. Their remains, many of which belonged to Paris' founders and first citizens, help make up the famed catacombs that run for miles five stories beneath the City of Light. But that story is not really the one that Legendary Pictures' new found footage film As Above/So Below is interested in telling. The movie, from sibling filmmakers John Erick and Drew Dowdle (Quarantine, Devil), follows archaeologist Scarlett Marlowe (Perdita Weeks) whose career has been spent pursuing legendary alchemist Nicolas Flamel’s Philosopher’s Stone, a fabled artifact that is said to be able to turn metal into gold and grant eternal life.
