On Friday night, it was revealed that NBC has opted against renewing Constantine for a second season, effectively cancelling the show unless Warner Bros. can find another home for the DC adaptation. Following the news, Arrow star Stephen Amell took to Twitter to lend his support to the show, offering to make a guest appearance as Oliver Queen should another network pick it up, and during the Wizard World Philadelphia Comic Con this weekend, Amell has revealed that discussions had taken place about a potential crossover between the two series.
“There is an opportunity for interconnectivity with any DC television show that exists,” said Amell (via Comic Book). “Like, as an example, yesterday Constantine was cancelled. And there is…yeah, I know, it’s brutal…it’s a good show, and it should come back. And it may come back, like there are various platforms where it could come back. Now, Constantine was an NBC show. I’m on The CW. I had had discussions with DC… so not NBC, not CW… but with DC Entertainment about guest starring on Constantine when it was still on the air. And that was and is still on the table… The reason that I was going to guest star on Constantine, at least the idea that we were throwing around was he’s an expert when it comes to the Lazarus Pit, which is now something that is a part of and will continue to be a part of Arrow.”
Amell went on to discuss the potential crossover opportunities between Warner Bros.’ various DC shows, stating that: “We have The Flash, we have Legends of Tomorrow, a new show which is directly connected to the Arrow universe, we have Supergirl… she got picked up, directed by my good friend Glen Winter, that pilot, I can’t wait to see it, I’m sure it’s going to be amazing… there’s Gotham obviously, and I’m missing something… Titans, there you go. So again I wouldn’t worry too much about the movie universe [being separate from the TV universe], because we have no shortage of options for me and other characters to populate.”
