This season of The Flash will also include another installment of The CW’s super-sized, four-show DC Comics crossover, with sister series Arrow, Supergirl, and Legends of Tomorrow. Kreisberg couldn’t spoil much of what’s to come during the epic event -- last year featured the super crew teaming up to battle the alien Dominators -- but did tease that this year’s crossover “really, truly is a four-hour movie.”
“Last season, it very much felt like, an episode of The Flash, and then it was definitely an episode of Arrow, and then it was definitely an episode of Legends,” he noted. “This time around, you won’t know what show it is, [based on] what episode it is. There’s a beginning to the story and then there’s an end to the story, and it covers the four hours. For that, we’re really proud. It’s huge, it’s the biggest thing we’ve ever done.”
The Flash airs Tuesdays at 8 p.m. ET/PT on The CW.
