Check out a brand new trailer for In Fear, a low-budget British horror movie that killed at Sundance and Frightfest. Featuring lines like, "We're not lost, we're in a maze" and "he had no face," this trailer is one big creep-out.

Apparently, this film was made without a full script, meaning actors Iain De Caestecker and Alice Englert improvised all their dialogue. And yes, De Caestecker is one half of Fitz-Simmmons in Agents of SHIELD — but he's also the star of the brilliant British horror series The Fades, and his horror chops look like they get put to good use here.

In Fear has been getting pretty much all rave reviews, and it comes to theaters in the U.K. on Nov. 15. No clue when it hits in Stateside. [Sci Fi Now]
