At today's Upfronts presentation, CW boss Mark Pedowitz announced that the Crisis on Infinite Earths Crossover will air in "5 hours over 2 quarters".
TVLine has since confirmed with sources that the five shows taking part in the crossover will be Arrow, The Flash, Supergirl, Batwoman (which premieres this fall) and Legends. Three of the five parts will air in December, and the other two — including an episode of Legends, which this year premieres at midseason — will follow in early 2020.
