Following two new teasers in which Oliver Queen and Barry Allen switch places, The CW has released the first Supergirl promo for the Elseworlds crossover featuring Melissa Benoist as Supergirl and Chyler Leigh as Alex Danvers with long hair and clearly not recognizing Kara.
Elseworlds will mark Ruby Rose’s first appearance as Batwoman, but the actress will also play the role in the Batwoman series in development for the 2019-20 season.
Newcomers to the Elseworlds cast also include Elizabeth Tulloch as Lois Lane, Cassandra Jean Amell (Stephen Amell’s real-life wife) as Nora Fries, the wife of Mr. Freeze, LaMonica Garrett (Designated Survivor) as The Monitor, and Jeremy Davies as Dr. John Deegan.
The crossover starts on Sunday, Dec. 9 with The Flash at 8 p.m., followed by Arrow on Dec. 10 at 8 p.m., and concluding Dec. 11 at the same time with Supergirl. DC’s Legends of Tomorrow is not part of the crossover this year.
