'Constantine' Is Back From the Dead on The CW's 'Arrow'! Details on the Big Crossover

Constantine fans, rejoice!

The one-and-done DC Comics drama, which NBC canceled back in May, is living on for one more day – but this time on The CW’s Arrow, it was announced Tuesday.

Constantine star Matt Ryan is expected to reprise his demon-hunting character John Constantine in the fifth episode of the upcoming fourth season, titled “Haunted.” (That episode also marks the debut of Thea’s new love interest Alex, played by Enlisted fave Parker Young, which ETonline broke Monday.)

For those unfamiliar with the character, he is a weather-worn exorcist and expert on the supernatural and the occult. He will provide critical support to Oliver Queen (Stephen Amell) when arrows aren’t enough.

The CW entertainment president Mark Pedowitz made the exciting announcement during his afternoon executive session at the Television Critics Association summer press tour, saying, “The series is no longer on the air and luckily one of our parent companies, Warner Bros., was the production company for Constantine. We worked with them and it’s a great one-shot episode.”

Ryan posted a video on Twitter shortly after the news, which was hinted at by Constantine showruner Daniel Cerone, telling fans in a tweet, “The Trench Coat is being dusted off.”

In the video, the British actor – wearing a black leather jacket and dark shirt surrounded by greenery – shared a special message for the Constantine and Arrow fans, thanking them for keeping the character alive and hinting at changes for season four: “The rumors are true. John is coming to Star City. I’ll see you this fall!” Ryan said.

“The introduction of magic and mysticism on the show this season has provided a truly organic opportunity for us to bring John Constantine to Arrow and The CW’s DC universe,” Arrow executive producer Marc Guggenheim said in a statement. “It will be a well-deserved tip of the hat to all the Constantine fans who were so incredibly supportive of that series.”

Fans had been clamoring for a crossover since NBC axed Constantine earlier this year, with Guggenheim telling Variety at the time that “there’s a lot of desire on everyone’s part” to establish the character as part of the same universe Arrow and The Flash currently belong in. “It would be wonderful and we certainly have a million ideas,” he said in May.

Amell was also similarly interested in bringing Ryan into the fold, tweeting on May 8, “#SaveConstantine – Hey TV Networks / Netflix and the like… If you pick up the show, I’ll guest star,” which prompted a response by Ryan, “man, it would be a real pleasure to explore these Guys dynamic #Constantine #SaveConstantine.”

“Can’t wait, Constantine & Queen want to get s**t done. Let’s make it happen,” Amell wrote back.

On Tuesday, Amell officially welcomed Ryan onto the Arrow team. 

We won’t have to wonder anymore!
