Technically, the first crossover between The CW's DCTV shows occurred between The Flash and Arrow as season 2 of the Green Arrow TV drama featured a backdoor pilot for the Scarlet Speedster's solo series. Ever since, each of the network's DC Comics superhero shows have featured a crossover miniseries that has seen aliens attack, an immortal madman on the rampage and bombs threaten to destroy Star City.
For the next crossover, showrunner Marc Guggenheim is teasing that the stakes might be smaller in scope but the outcome will still have important developments in its aftermath.
"If we end up doing what we’re talking about doing, it’s going to be pretty cool. The crossover is always the most challenging thing we do, but it’s also the most fun. Every year we feel the pressure [to top ourselves]. I feel like each crossover has topped the previous one. Topping last year’s, that’s a high bar, if for no other reason than what do you do that’s bigger than aliens?
We’ve got some very, very exciting ideas…. Very early on in the process of doing last year’s crossover, Greg [Berlanti] said there’s probably no way to get bigger than aliens, so the best way to make the [next] crossover especially epic is if you can’t increase the bombast, increase the emotional stakes and the emotional payoffs, so that’s a very oblique comment on where our heads are at for this season."
Between Arrow, The Flash, Supergirl and Legends of Tomorrow, it will certainly be interesting to see what Guggenheim and co. cook up with such a diverse cast of superheroes. With a more emotional-focused crossover perhaps some familiar faces and foes from the past will be returning?
