A haunting and unsettling psychological horror film, "The Mafu Cage" (1978) follows two sisters, Ellen and Cissy, as they inhabit a crumbling mansion in Los Angeles, where Cissy keeps a menagerie of monkeys locked in a cage that once belonged to their late father. The film is a rare and disturbing intensity, building tension through its exploration of sibling relationship, obsession, and the descent into madness. Directed by Karen Arthur and starring Carol Kane and Lee Grant, "The Mafu Cage" premiered at the 1978 Cannes Film Festival before being met with difficulty in North America, ultimately attaining cult status on home media releases.
