As a horror fan you probably saw 2012 found-footage anthology movie V/H/S. Possibly the most memorable portion of that film was the segment entitled 'Amateur Night', when foxy Hannah Fierman turned into a blood-hungry, face-splitting creature of terror.
Watch it (again) if you need to (re)live the scares...
If you didn't like V/H/S as a movie, stop reading now. If you did enjoy V/H/S, you'll be pleased to know that Fierman herself is returning to adapt the V/H/S short into a full-length movie in its own right.
Little is known about the project, other than that it will be called Siren, penned by Ben Collins and Luke Piotrowski. The synopsis reads (unsurprisingly!) just like the original 'Amateur Night' short:
A bachelor party that becomes a savage fight for survival when the groomsmen unwittingly unleash a fabled predator upon the festivities.
