This week, it’s finally time to take the elevator down to the testing floor. To break down all the revelations in Season 2 Episode 7, Ben and Adam are joined by Dichen Lachman, who plays Gemma / Ms. Casey. She shares what it was like filming in a brand new location with a new cast of characters, how she and Adam built out the relationship between Gemma and Mark, and the origin story of Ms. Casey’s iconic wig. Then, Ben sits down with Jessica Lee Gagné, Severance’s main cinematographer and director of the episode, to talk about why she chose this episode as her directorial debut. Plus: why you should never offer up your own house as a filming location.
