Sam is struggling. Being a human has never been simple for him. He just feels like a different kind of creature. Sam’s family don’t understand. But then they barely understand themselves. Now, trapped in a stuffy inpatient clinic undergoing family therapy, they must find new ways to communicate with each other so that, one way or another, Sam can be released from captivity. The world premiere of Ruby Thomas' The Animal Kingdom, directed by Lucy Morrison, is an observation of family dynamics told with wit and compassion. Ruby Thomas returns to Hampstead Theatre, following the premiere of her first full-length play Either in 2019. In 2020, Ruby wrote a piece for the Royal Court’s Living Newspaper, and she has also had short plays performed at the Old Red Lion, Platform Southwark, the White Bear and Theatre503. Lucy Morrison makes her Hampstead debut. An Associate Director at the Royal Court, her credits include Scenes with girls (Royal Court), The Woods (Royal Court) and Little on the inside (Almeida Festival/Clean Break). The play contains strong language, themes of depression and anxiety and multiple references to suicide attempts and self-harm.
