The casts of ‘Arrow,’ ‘The Flash’, ‘Legends of Tomorrow,’ and ‘Supergirl’ are jumping in feet-first in a new crossover photo

Let’s face it: the upcoming crossover between Supergirl and the three Arrowverse shows is arguably the most exciting thing coming to our screens this fall. Forget Flashpoint, forget the Justice League of America, forget Superman — we’re all counting down the days until the epic ArrowFlashLegendsSupergirl mega-crossover.

In the days since Comic-Con last month, we’ve gotten a few more teases from producers about what to expect from the big event, but a new tweet from Arrow star Stephen Amell may be our first tease of the crossover in action:

The uncaptioned photo shows the legs and feet of Green Arrow (Amell), The Flash (Grant Gustin), Supergirl (Melissa Benoist), White Canary (Caity Lotz), and the Atom (Brandon Routh).

Now, it’s a little early to be filming the crossover episodes, as it was just confirmed by executive producer Greg Berlanti earlier this week that each show’s writers had just begun to break the story for the event.

So what’s going on here? Most likely the actors are filming a promo for the upcoming crossover and/or participating in a group photo shoot. (Both possibilities have since been unofficially confirmed by other crew members on Twitter).
