New details are made known about the upcoming Arrowverse crossover involving Green Arrow, The Flash, Supergirl and Batwoman in that it will involve both Arham Asylum and Gotham City.
The latest casting news regarding the crossover explains why Green Arrow (Stephen Amell), the Flash (Grant Gustin), and Supergirl (Melissa Benoist) set foot in Gotham City, where they meet up with Batwoman (Ruby Rose).
Actor Jeremy Davies, known for Lost, has been cast in the role of Dr. John Deegan, a doctor at Arkham Asylum for the Criminally Insane who might be crazier than the inmates he treats. According to the official description for the character, Dr. John Deegan’s “machinations will draw Green Arrow, the Flash and Supergirl to Gotham City.”
It’s also known that the upcoming Arrowverse crossover will feature Tyler Hoechlin back as Superman and introduce Lois Lane (played by Elizabeth Tulloch) and Nora Fries (played by Cassandra Jean Amell).
So based on the description of Arkham Asylum, we see that whatever Dr. John Deegan is doing there, somehow brings all these superheroes together, which obviously sounds like something really big (and potentially really evil).
The three-night Arrowverse crossover kicks off Sunday, Dec. 9 with The Flash followed by Monday, Dec. 10 with Arrow, and concludes Tuesday, Dec. 11 with Supergirl.
