Last year, franchise creator James DeMonaco (writer/director of The Purge, The Purge: Anarchy and The Purge: Election Year) revealed that he plans for the fifth movie in the series to be the last.
According to Deadline, Hunger Games and True Detective actress Leven Rambin has joined the yet-to-be-titled Purge 5 from Universal Pictures and Blumhouse Pictures.
The Purge series kicked off in 2013 with the first film, a smaller scale home-invasion thriller starring Ethan Hawke.
The series made the transition to television last year with the 10-episode event series of the same name on USA network.
