Blair Witch 'secret sequel' gets a claustrophobic new trailer

Adam Wingard's horror is a follow-up to 1999's found-footage modern classic

About three months ago, we introduced you to a creepy trailer for The Woods, a new horror film from director Adam Wingard who we branded the genre's "saviour."

Wingard then went to reveal that his new film is, in fact, a secret sequel to seminal horror The Blair Witch Project (1999).

A trailer for the new film - simply titled Blair Witch - debuted at San Diego Comic-Con last month providing a chilling connection to the seminal found-footage horror film released in 1999.

Now, an extended fresh look has surfaced and, as you may no doubt expect, it's not for the faint-hearted.

The original saw characters named Heather, Joshua and Michael venture into Burkittsville woods in Maryland to investigate the mystery of the Blair Witch. This film's group of characters return to the same location led by Heather's brother who wants to discover what happened to his sister all those years ago.

Wingard - director of The Guest and Netflix's upcoming live-action version of Death Note - has himself described Blair Witch as his first 'full on "shit your pants" horror film". You can find out whether or not that's the case when it's released in the UK on 16 September.
