Supergirl, Arrow, Legends of Tomorrow, and The Flash will unite the Arrowverse this fall.
IGN reveals that another major DC TV crossover is coming to The CW after the network announced during the Television Critics Association summer press tour that the four-show crossover event will commence on Monday, November 27 with Supergirl, followed by Arrow, which for that week will move to Monday from its new Thursday time slot. The crossover will then conclude on Tuesday, November 28, starting off the night with The Flash and then concluding with Legends of Tomorrow.
The CW President Mark Pedowitz said:
“Last year's crossover was the most successful week, I believe, in CW history. We felt that in this particular case we already had Flash and Legends paired. It would be better and tighter to do it like a two-two hours mini-series”.
He noted the network hasn't ruled out going back to a four-night crossover next year. In other Arrowverse news, Danny Trejo will appear in The Flash season 4, Lost's Michael Emerson will star in Arrow's sixth season in an unspecified role, Captain Cold actor Wentworth Miller and Rip Hunter actor Arthur Darvill are returning as recurring guest stars for DC's Legends of Tomorrow: Season 3, and Supergirl will add four new cast members including Heroes alum Adrian Pasdar will portray DC villain and ruthless real estate developer Morgan Edge.
Supergirl season 3 premieres Monday, October 9 at 8pm on The CW, The Flash season 4 on Tuesday October 10 at 8pm and Legends of Tomorrow that same night at 9pm. Arrow season 6 premieres on the show’s new day and time slot Thursday October 12 at 9pm.
