‘Elseworlds’ First Promo: Oliver and Iris Kiss as ‘Arrowverse’ Crossover Rewrites History (Video)

Arrow and The Flash swap lives this December on The CW

When The CW teased that The Flash and Arrow would be trading places during the upcoming “Elseworlds” crossover event, they weren’t kidding.

In the first promo for the annual three-night event, we see Iris West-Allen (“The Flash”) kissing Oliver Queen (“Arrow”). Wait, what? Yes, Oliver and Iris, locking lips — and then she calls him Barry Allen. Based on previous hints about this year’s Arrowverse crossover, we know Barry (Grant Gustin) and Oliver (Stephen Amell) are going to be swapping supersuits, and it looks like switching lives entirely.

The crossover will see the return of Tyler Hoechlin as Superman, the introduction of Elizabeth Tulloch as Lois Lane, and the debut of Ruby Rose’s out Batwoman. Other new cast members include Jeremy Davies as Dr. John Deegan, LaMonica Garrett as The Monitor, and Cassandra Jean Amell as  Nora Fries, wife of Mr. Freeze.

“Elseworlds” will cause a few shakeups to the network’s regular schedule. “The Flash,” which usually airs on Tuesdays, will kick off the three-night crossover on Sunday, Dec. 9, followed by “Arrow” on its regular Monday night, and then “Supergirl” — which airs on Sundays this season — in a special slot on Tuesday.

Watch the teaser above.

The Arrowverse crossover event, “Elseworlds,” will air Sunday, Dec. 9 through Tuesday, Dec. 11 on The CW.
