Indie jack-of-all-trades Mark Duplass’ roots in the mumblecore film movement have given him a strong base for understanding how to capture the ups and downs of human relationships. His writing on films such as The Puffy Chair (2005), Jeff, Who Lives at Home (2011), and Blue Jay (2016) all focus on deconstructing what keeps people together and what threatens to tear them apart. The monsters in these stories are the frantic yearning for partnership, the unexpected ways people change, and past mistakes that linger like ghosts. Take these themes a few steps further, as Duplass has done in Baghead (2008), Creep (2014), and Creep 2 (2017), and you have yourself a strikingly magnetic horror film.
