While it’s still okay to be sad that NBC canceled “Constantine” after only one season, the timing really couldn’t have been any better in terms of getting Matt Ryan to reprise his titular role on The CW’s “Arrow.”

“As is true on ‘Arrow,’ we didn’t want to just bring Constantine in for the sake of bringing him in,” executive producer Wendy Mericle tells Zap2it. “We wanted to do it organically and it just so happened that this season that we’re exploring themes of magic and mysticism and specifically we needed someone to perform that ritual on Sara (Caity Lotz) to bring her back.”

Once those pieces were in place, Mericle says it “just felt perfect.”

Besides, with Damien Darhk (Neal McDonough) using his mystic powers to make all sorts of trouble in Star City, having a master of the occult like Constantine on their side is a good thing. While he may never be seen or heard from by fans the rest of the season, he could easily be a long distance dark arts advisor to Oliver.

Keeping that character in the minds of fans would create the distinct possibility that Ryan will again don the coat in the future.

By the way, for those wondering — yes, that is John’s actual coat from the series. Mericle confirms, “We got to use all of the original props from the series and the wardrobe.”

As for why John’s wearing the short version of the coat — after upgrading to the long one in the “Constantine” series finale — that remains a mystery.

“Arrow” airs Wednesdays at 8 p.m. ET/PT on The CW.
