Late Night with the Devil has an infinitely-replicable concept.
Take an era-specific form of popular filmed-entertainment, and then imagine what would happen if shit got real while filming, reveling in the period and genre aesthetics from the chosen type of moving-image media.
Think of it like a franchise of “found-footage” spiritual sequels to Late Night with the Devil — similar to the relationship between Ti West’s X, Pearl, and the upcoming MaXXXine, where each installment resides in a different horror sub-genre.
You could cast David Dastmalchian in all of them to test his newly-showcased leading-man range…or you treat the franchise as a series of opportunities to let a different character-actor shine in a main role.
