“Arrow” and Supernatural are two of the most popular shows on The CW. Although The CW is known for its supersized crossovers, such as the last year’s superhero crossover that included “Arrow,” “The Flash,” “Supergirl,” and “Legends of Tomorrow,” a crossover between “Arrow” and “Supernatural” seems like an unlikely mix - given the difference in their genres. However, actor Stephen Amell said it is possible.

The idea was first pitched last year during Entertainment Weekly’s Pop Fest, where fans from the popular The CW TV shows gathered. Backstage, Stephen Amell posed with “Supernatural” actors Jared Padalecki and Jensen Ackles, as well as Grant Gustin of “The Flash,” Caity Lotz from “Legends of Tomorrow” and “Supergirl” herself Melissa Benoist.

The photo, which Amell shared on Instagram, was captioned: “This is the crossover we need.”

It is evident that The CW crew is one tight-knit family and they would all be comfortable filming one massive episode together.

It’s Up to The “Supernatural” Boys

In a recent Facebook Live Q&A, Amell once again brought up the idea of a DC and “Supernatural” crossover on The CW.

According to Stephen Amell, the possibility of "Arrow/Supernatural" crossover will still depend to Jensen and Jared. According to Cinemablend, the actor heard that Jensen and Jared will be getting a "Supernatural" spin-off, which is definitely an event to be excited about; however, if the crossover would fit into Jensen and Jared's schedule, the Canadian actor will certainly go for "Arrow/Supernatural" crossover.

“Supernatural” has been broadcasting on The CW since September 2005 and is one of the longest-running shows in television history. Both Ackles and Padalecki have been with The CW for the longest time, making them seniors to Amell, Grant and the rest of the DC superhero squad.

Amell added, “I’m totally up for it.

I'm not trying to pass the buck, but the buck is now sitting at their feet.”

DC and “Supernatural” Cross-Over Pros and Cons

If there’s any DC superhero TV show that would work well with “Supernatural,” it’s going to be “Arrow.” Oliver Queen fits in with the Winchester brothers, given his no-nonsense attitude. Oliver was also deserted in the island of Lian Yu for a very long time, and he’s probably witnessed a lot of supernatural incidents happened there.

For one, John Constantine has appeared on “Arrow” several times. Those familiar with the DC Comics would know that Constantine battles supernatural elements, something Sam and Dean Winchester known a lot about.

The only potential problem, for now, is that “Arrow” takes place in the fictional city Star City, while “Supernatural” is set in actual locations around the United States.
