Jeremy Davies (Lost, Justified, Sleepy Hollow, American Gods) has been cast as the central villain of the annual DC CW crossover event per The Hollywood Reporter.
Davies will play John Deegan, a doctor at Arkham Asylum for the Criminally Insane in Gotham City who might just be crazier than the inmates he treats.

Tyler Hoechlin's Superman will appear in all three episodes of the crossover. Elizabeth Tulloch was recently cast as Lois Lane and Cassandra Jean Amell will play Nora Fries whose characters husband (Mr. Freeze) will not be apart of the crossover.
