WHEN NBC pulled the plug on Constantine fans rallied to rescue it. It was a pretty interesting and engaging show. It did more in one season, than most shows did with multiple seasons.
Arrow star Stephen Amell said that there were talks of him making an appearance on an episode of Constantine, but since NBC cancelled the series, that possibility never came to be. Fortunately for fans, there may still be a chance for John Constantine to appear on Arrow, in spite of his own show not being on a network. Arrow executive producer Wendy Mericle told IGN that she's optimistic that Matt Ryan's version of John Constantine could still make his way to The CW.
"Yeah, we really want to do it," Mericle said. "It's something we've been talking to DC about and it's just a question of some political things, but also the actor's schedule. We're trying to work it out, but we don't know 100 percent if it's going to happen."
Originally, discussions about Constantine making an Arrow cameo centered on the mystic being an entry point into the supernatural side of the DC Universe for Oliver Queen. Since Arrow has already already been exposed to the strange and mystical stuff outside of typical crime fighting, (the Lazarus Pit that resurrected his sister from the dead, Damien Darhk) Some speculate that this is the perfect time to introduce him to the world of Constantine.
There is even talk that the creators of the Constantine show are trying to convince Warner Bros. television and production partners into a second season for Constantine. Although it may be possible, it will be a long stretch considering that all the expired contracts would now have to be reworked in order to retain the original staff and cast.
Arrow returns in October on The CW.
