The titular island in the movie is Staten Island, and it will be the home of the first Purge following the rise of the New Founding Fathers of America (a.k.a. the NFFA).
While we can’t be 100 percent certain, we can probably guess that Y’lan Noel and Lex Scott Davis will be playing two individuals who get caught on the island at the (extremely) wrong time.
This casting news comes to us from the folks at the Tracking Board, though unfortunately there is no information currently available regarding what roles they will be playing within the film The Purge: The Island, which is based on a script by franchise creator James DeMonaco, but is being made by director Gerard McMurray (Burning Sands), is a prequel that will expose the origins of the vicious social experiment.
