The Making Of: As Above, So Below

As Above, So Below is unsettling for a few reasons, although predominately due to its incredible setting.

Set in the catacombs of Paris, with human remains aplenty, it's essentially The Blair Witch Projec t by way of The Descent . So obviously we jumped at the chance to head into the catacombs ourselves to interview the stars, director and writer.

Watch on to see where the team got the inspiration for the found footage horror, what on-set mischief they got up to whilst filming in the caves, sequel ideas and much more.

As Above, So Below is in UK cinemas from 29 August 2014.
