Keanu Reeves was looking ruff and ready at the premiere of Knock Knock. The star stepped out in Hollywood sporting a beard. Keeping it smart yet casual in a tshirt with suit. Lorenza Izza also stars in the film and plays one of the stranded young women who unexpectedly knock at a door for help, with the chance encounter turning dark. For the event she opted for a playful look in a backless dress, wearing her hair up with a sparkly headband. Ana De Armas takes on the role of the other attractive wandering stranger. She showed some skin with a plunging neckline.
