VIDEO: Arrow-verse Crossover Debut Posters & First Trailer!

We’re less than a week out from the start of the most epic crossover event ever!

Arrow, The Flash, Supergirl and DC’s Legends of Tomorrow will intertwine in a four-episode, four-show event that starts on Monday, November 28th!

Kicking off on Supergirl, the Dominators take over Central City, and Barry (Grant Gustin) speeds over to Star City to ask the Green Arrow (Stephen Amell) for help in stopping them.

Realizing the battle against the Dominators is bigger than they thought, they track down the Legends of Tomorrow, and Barry and Cisco (Carlos Valdes) create a breach to bring back a secret weapon — Supergirl (Melissa Benoist).

Check out the first trailer below and take a look at the sneak peek slideshow on JJJ!
