Arrowverse showrunners Wendy Mericle, Todd Helbing and Phil Klemmer spoke with THR to give fans a preview on what to expect from this season's four-way crossover of The Flash, Arrow, Supergirl and Legends of Tomorrow.
Titled "Crisis on Earth X," the two-parter will bring the gang together on Barry and Iris' wedding, but things go awry when villains from Earth-X attack the ceremony.
Read the EPs' preview below:
Mericle on Arrow:
The biggest surprise will be the emotional component of the crossover.
I don't think anyone is going to see that coming. It's very much a dark love story. It's the underpinnings of that that will make the Earth-X element a real contrast to that. Oliver [Stephen Amell] has a big role to play in it, and it's bigger and better than any crossover we've done in the past. It's going to be epic.
Helbing on The Flash:
In typical hero-villain fashion, the wedding is not the wedding that Barry (Grant Gustin) and Iris (Candice Patton) probably dreamed of.
This crossover is so different. Any time you're trying to keep the narrative going on four different shows, it's challenging. The Earth-X scenario we put everyone in really played into the story that we wanted to tell.
Klemmer on Legends of Tomorrow:
You'll be most surprised that Legends is capable of making our audience cry.
I thought last season really leaned into the comedy, and that season three we tripled down on that. There's some ludicrous moments. Things get bananas, and yet in this crossover, we have this thing that happens that will honestly move you to tears.
