The fourth film in the franchise is actually the first… in that it’s an origin story for – you guessed it – the Purge itself. The “New Founding Fathers of America” have decided to use citizens as guinea pigs to test a theory that venting aggression for one night each year will lower crime for all other nights. Some people take issue with this experiment and decide to protest. As you might suspect, protesting during the Purge does not go well – particularly for one Staten Island family stranded in the melee. Directed by Gerard McMurray and written by James Demonaco (director of the first three Purge films), and starring Y'Lan Noel, Lex Scott Davis, Joivan Wade, Luna Lauren Velez, and Marisa Tomei.
