Frank Grillo said in an interview that he would only return if the script is really good and James DeMonacco will have something to do with the movie.
James Demonaco said in a interview that he doesn't think he will direct this fourth film only write and produce it.
The poster for the film shows a picture of a red hat with the slogan "The First Purge." This is a reference to President Donald Trump's red "Make America Great Again" hat which was used throughout his presidential campaign.
Tentatively called "Purge: Island". This movie was filmed in Buffalo, NY and doubled as Staten Island, NY.
Frank Grillo will not reprise his role as Sgt. Leo Barnes in this fourth installment
