"The Flash," "Arrow," "Supergirl" and "The Legends of Tomorrow" will have a huge crossover event next season.

According to E! News, all three shows on The CW have previously crossed over, but "Supergirl's" recent transfer from CBS to the network would mean that the franchise is complete for now.

While speaking with the publication The CW president Mark Pedowitz said that a crossover is imminent.

Meanwhile, some cast members from the four shows revealed which actors from another series they want to work with.

"Arrow" lead star Stephen Amell said that he wants to work with "Supergirl" lead star Melissa Benoist.

On the show, Amell plays the role of Oliver Queen, while Benoist gives life to the character Supergirl.

"Melissa Benoist. We haven't been on screen together. Also, I still haven't been on screen with Victor Garber, and that's bullsh*t," Amell said.

"The Flash" star Jesse L. Martin said that he wants to work with "Supergirl" star Calista Flockhart. "The Flash" lead star Grant Gustin wants to have scenes with "Legends of Tomorrow" actor Brandon Routh.

"I think Barry and Ray have a really funny dynamic," he said.

Meanwhile, "The Flash" star Carlos Valdes wants to be able to work with "Supergirl" actor Jeremy Jordan.

According to him, it would be fun to work with Jordan because they have some similarities.

"Legends of Tomorrow" actress Caity Lotz said that she wants to work with Danielle Panabaker's Killer Frost.

As of late, it is still unclear when the crossover will actually be.

"The Flash" season 3, "Arrow" season 5, "Legends of Tomorrow" and "Supergirl" season 2 will all return to The CW sometime this year.
