It would be two more years before Ana de Armas would appear in Blade Runner 2049 and Knock Knock was the first Keanu Reeves movie to come out after the first John Wick film.
Knock Knock, which is a remake of the 1977 film Death Game, is, not great by most accounts.
Rotten Tomatoes currently lists the film with a 36% score, and it’s probably not surprising the movie wasn’t put in theaters domestically.
The fact is that while two of the film’s main stars are huge right now, that wasn’t the case in 2015.
