Fans of Arrow and The Flash have gotten used to both shows having crossovers with each other over the past season. But unlike Marvel, who has all their network shows located on ABC, DC shows have been spread out over several networks, provoking questions as to whether the CW offerings could cross over with shows like Gotham or Constantine. While the former seems unlikely (for now), an opportunity almost occurred between the latter and Arrow, with series star Stephen Amell discussing an opportunity to guest star on the now-cancelled Constantine.
According to Comicbook.com, Amell revealed at the Wizard World Philadelphia Comic Con that when Constantine was still on the air, there were talks between him and the folks at DC Entertainment about him appearing on an episode of the supernatural series. According to the actor:
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.
Although Arrow has explored special abilities through characters like Deathstroke and Barry Allen, there haven’t been specific indications of whether magic exists in this universe. However, it was the recent introduction of the Lazarus Pit (the mystical waters that heal injuries and have kept Ra’s al Ghul alive for centuries) this season which Amell says would have allowed the show to eventually cross over with DC’s occult detective.
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.
NBC cancelled Constantine last Friday due to less-than-stellar ratings. The show is currently being shopped around to other networks, however, so there may still be hope for it to return for Season 2. Amell has also expressed his support for the show to return. Soon after the supernatural series’ cancellation was announced, he sent out a tweet saying that if the show was picked up again, he would guest-star on it.
Whether or not Constantine will be resurrected is unclear, but if it is, crossing over with Arrow (and maybe The Flash at a later date) would be beneficial for both shows. Constantine would get to establish connections with the CW’s successful DC TV universe, and Arrow would get to expand on the mystical forces at work within its world. The prospect of seeing the trench coat-wearing con-man and the emerald-clothed archer working together against dark forces, be they supernatural or down-to-earth, would make almost any comic book fan excited.
