Crossover Casting: Jeremy Davies cast as Dr John Deegan, Arkham Doctor

"Dr. John Deegan is a doctor at Arkham Asylum For the Criminally Insane in Gotham City, but he might just be crazier than the inmates he treats. His machinations will draw Green Arrow, The Flash and Supergirl to Gotham City."

i. love. Jeremy Davies.

the only John Deegan I know of in the comics is Jack Deegan aka Jack of Diamonds, who was a lacky of the Joker's

like 1940s joker
