Back in May, NBC canceled the first-year seriesConstantine, as many expected the network would, due to low ratings, with the show searching for a new home on Netflix, Amazon and a number of other networks and streaming services. Just a few days after the cancellation,ArrowstarStephen Amellproclaimed on hisTwitterpage that he would guest star, if someone stepped up and saved the series. Alas, it never came to be, with executive producer Daniel Cerone confirming thatConstantine’s search for a new home has come up empty. However, while promoting the new season ofArrowatComic-Conlast week, executive producer Wendy Mericle revealed they are still trying to bring the character aboard forSeason 4

“Yeah, we really want to do it. It’s something we’ve been talking toDC Comicsabout 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, but we’re really optimistic and we would love to have him.”

While he isn’t specifically mentioned by name, it is believed that Wendy Mericle was referring toMatt Ryan, who playedJohn Constantineon the short-lived NBC series. If it does happen, it would certainly be a unique crossover, simply becauseConstantineisn’t on the air anymore. Just a few days afterStephen Amellrevealed he would guest star onConstantine, the actor confirmed that he actually had discussions with DC about crossing over to the NBC series, which could pave the way forMatt Ryanto appear onArrow. Here’s what he had to say during an appearance at the Wizard World Philly convention in May.

“There is an opportunity for interconnectivity with any DC television show that exists. Like, as an example, yesterday Constantine was cancelled. 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.Constantineis an NBC show, I’m on the CW. I had discussions with DC Comics – not NBC or the CW – DC Entertainment about guest starring onConstantinewhen it was on the air. That was and is on the table. The reason that I was going to guest star onConstantine, at least the idea that we were throwing around, was [Constantine’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.”

As of now, there is very little we know about Arrow Season 4, except thatNeal McDonoughwas recently cast as the season’s main villain, Damien Dahrk, and bothArrowand Diggle (David Ramsey) will get new costumes.Arrow Season 3ended with Oliver leaving Starling City with Felicity (Emily Bett Rickards), while Malcolm Merlyn (John Barrowman) took over as the new Ra’s al Ghul. We’ll have to wait and see how the Lazarus Pit comes into play this season, but we know it will also be featured in the spinoffDC’s Legends of Tomorrow, since this is howCaity Lotz’s Sara Lance, a.k.a. Black Canary, was brought back from the dead and transformed into the White Canary. Would you like to seeConstantinepop up onArrowthis season?
