Alexander Skarsgard and Andrea Riseborough look gaunt and tortured in the first photos to emerge from the Vancouver set of indie horror flick “Hidden.” Matt and Ross Duffer wrote the script and are currently directing the film that follows a family hiding out in a bomb shelter after escaping from a mysterious outbreak.

No further details are available, though the images do give some vague clues. Skarsgard and Riseborough play husband and wife, as well as father and mother to a daughter, played by Emily Alyn Lind and judging by their pallor and threadbare, dirty clothing, we appear to be witnessing a scene that follows the family as they emerge from their protective bomb shelter. Riseborough is seen covering her daughter’s mouth to silence her, while Skarsgard glares suspiciously at something or someone off camera. Could a mysterious visitor be on the premises?
