Batwoman won't be the only familiar face from Gotham City appearing in December's Arrowverse crossover: The CW has just cast Cassandra Jean Amell (yes, the wife of Arrow star Stephen) in the role of Nora Fries. No details were provided as to whether Amell's version of the character will be alive and well or in cryostasis at the time of her introduction. Nora Fries was one of the characters created originally for the Batman: The Animated Series.
