Cory Michael Smith, known for playing Private Bergen in Camp X-Ray is the new Riddler. His resume, however, is short. Filming on his second film, Carol, starring Rooney Mara and Cate Blanchett, is currently underway. Other than that, it he was in a short called Dog Food and some episode of Oliver Kitteridge. Talk about a fast rise!
That and he certainly looks the part!
