Stephen Amell Teases Epic CW Superhero Crossover Event with BTS Pic from Set

The CW

When the news was announced that Supergirl would be moving to the CW’s roster -- alongside fellow DC shows Arrow, The Flash and Legends of Tomorrow -- for its second season, many fans had the same question: Does this mean a team-up?

“It’s only fitting,” Supergirl star Melissa Benoisttold ET back in June. “We’re all in the same place now!”

Now, that epic crossover is officially underway! Arrow star Stephen Amell tweeted a pic from set on Sunday, teasing some of DC Comic’s finest in costume for the four-show event.

We spot The Flash’s (Grant Gustin) red boots, Sara Lance’s (Caity Lotz) White Canary kicks, Ray Palmer’s (Brandon Routh) Atom suit, and another pair of red boots which could belong to either Thea Queen (Willa Holland), a.k.a Speedy, or Supergirl herself. What a team!

So, is there anyone on the CW who won’t be appearing in the crossover event? Probably Supernatural stars Jared Padalecki and Jensen Ackles, who got rebellious on The Flash set on Monday.

“Hangin on the #TheFlash set w/@jarpad,” Ackles captioned a video which showed the two snacking and snoozing despite explicit signage warning them not to. “Hey @grantgust how do u get any work done with all these rules? #NeedNaps.”

If the Winchester boys show up in the crossover, it’ll really be a CW showdown!

ET spoke to Amell and his castmates at Comic-Con back in July, where they dished on what else to expect from the show’s upcoming fifth season.

"It really is about the formation of a new team," Amell said. "The team is what's necessary to really affect change."
