Fans are whole-heartedly anticipating DC’s crossover Elseworlds and a new poster has just increased the temperature further.

The new poster features Arrow’s Stephen Amell wearing The Flash costume while Flash’s Grant Gustin sporting Arrow’s appearance. This has driven fans crazy, and they have been sharing their responses ever since.

Elseworlds will undoubtedly be special, as it not only features these two heroes switching places but also shows the return of Superman reportedly in a black costume. It will see the debut of Lois Lane in the Arrowverse and the introduction of Ruby Rose’s Batwoman.

Arrow star Stephen Amell previously admitted that Elseworlds is the best crossover so far. Amell said the following during a Facebook Q&A:

“The crossover is f****** bananas. It’s crazy… I think that this will be the best crossover event that we do. And not just the best but the best by a really, really wide margin. And I think that last year was fantastic. Crisis on Earth X, I think that’s what it was called, that was pretty crazy and getting to play doppelgängers was pretty crazy. When Greg Berlanti first talked to me about why he wanted to do crossovers, it was because it’s for the fans. It’s so people can watch characters and scenarios that combine their favorite things on TV or introduce them to new things on TV. But you also get this license to do things that we could never do in the vacuum — especially on Arrow — that we can never do in the vacuum of just our show.”

Here are the best fan reactions:
