The Daily Mail shared photos of Grant Gustin and Ruby Rose goofing off on set between filming scenes for crossover. They appear together for the first time since last year's crossover "Elseworlds," which introduced the Arrowverse's Gotham City.
Following Batwoman's debut in the previous crossover, she received her own DCTV series on The CW, which premiered earlier this month to positive critical reviews and impressive viewership totals for the network.
The upcoming Crisis has been foretold since The Flash's series premiere in 2014, as a cataclysmic event for the fate of the entire DCTV Multiverse. An article from the future predicts The Scarlet Speedster's death during the epic confrontation between the Monitor and Anti-Monitor. What role Batwoman plays in the crossover has yet to be seen.
"Crisis on Infinite Earths" begins Sunday, December 8 at 8 pm ET/PT on Supergirl, then continues in Batwoman on Monday, December 8 at 8 pm ET/PT and in The Flash on Tuesday, December 10 at 8 pm ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, January 14 in Arrow at 8 pm ET/PT and in DC's Legends of Tomorrow at 9 pm ET/PT.
