The American supernatural drama TV series “Constantine” based on DC Comics only lasted for one full season on NBC before the network decided to cancel its Season 2 after its Season 1 finale.

Many DC fans really felt disappointed with the decision of NBC not to renew the show for its second season because “Constantine” is contextually rich in content. Because it is based on DC Comics, it has plenty of stories to tell, and most of them are really original.

Unfortunately, the TV series was aired on NBC instead of The CW which is now home to three TV series based on DC Comics.

At the time when “Constantine” started airing on NBC, the first TV series on The CW based on DC Comics, “Arrow,” has already bred a spinoff TV series which is “The Flash.”

“The Flash” is now on its second season on The CW and it looks like it will be renewed for the next few more seasons. Subsequently, “Legends of Tomorrow” a second spinoff TV series from “Arrow” has just started airing on The CW this week for its premiere season.

Still, there are also two TV series based on DC Comics that are now airing on other networks other than The CW, including “Gotham” on Fox and “Supergirl” on CBS.

Leaving the door open

The showrunner and cast members of “Arrow” also acknowledge that “Constantine” is part of the DC Comics universe which is the reason why the character John Constantine, played by Welsh actor Matt Ryan, guested in the fifth episode of its current fourth season.

The one-episode appearance of Matt Ryan as John Constantine actually left the door open for The CW to bring back the character through a possible TV series sometime in the future. However, as of this time, there seems to be no discussion at all about such possibility.

John Constantine appeared on the episode of “Arrow” titled “Haunted” as he was sought by Oliver Queen a.k.a. the Green Arrow, played by Stephen Amell, to help in dealing with Sara Lance, played by Caity Lotz, as she has become a danger to practically everyone after her magical resurrection in the Lazarus Pit turned her wild, unpredictable, and more deadly.

Immediately after Matt Ryan’s cameo appearance on “Arrow,” rumors started swirling that the executive producers of the new American superhero drama TV series “Legends of Tomorrow” also on The CW, are now considering to include John Constantine in Season 2 of the show sometime in 2017.

But since Season 1 of “Legends of Tomorrow” has yet to premiere when those reports started coming out, it is really too premature to even think about its Season 2 or the possible guesting or inclusion of John Constantine on the roster of cast members, notes the International Business Times of UK.

A hypothetical plan

In addition, Season 2 of “Legends of Tomorrow” is still hypothetical at this time given the reports that the show is very expensive to produce. There are even reports that the show might even be replaced by a totally different show.

More than the prospect of John Constantine joining the cast of “Legends of Tomorrow” for its still hypothetical Season 2, there are now reports going around that Matt Ryan is also being eyed to reprise the role not in another TV series but on the big screen.

Accordingly, critically-acclaimed screenwriter, director and producer Guillermo del Toro is now working on the script of a movie based on DC Comics tentatively titled “Justice League Dark.”

Interestingly, Constantine’s character has been a prominent fixture in the movie script, according to sources.

When told about this exciting prospect, Matt Ryan said that he is a huge fan of Guillermo del Toro because he is such an amazing director and he loves his work.

He also said that the “Justice League Dark” comics are also quite amazing and he would love that his character John Constantine be considered for it. Ryan also said that when actors do a character for TV, they do it for TV. But when they do it for a movie, it’s different.

Following Matt Ryan’s guesting stint on “Arrow” as John Constantine, showrunner Wendy Mericle said that it is definitely not the last that the Green Arrow and Constantine will see each other again on the TV series.
