If DC's Legends of Tomorrow is renewed for season 4, then Matt Ryan's John Constantine will be joining the crew on the Waverider as a series regular. Ryan portrayed the character in his own TV show, Constantine, which aired on NBC for only one season from 2014-2015. Since then he has appeared on both Arrow and Legends of Tomorrow and will also voice the character in the upcoming animated Constantine series airing on CW Seed.
Constantine has played a significant role in the current season of Legends of Tomorrow already. He was the one who told the team about the demon known as Mallus who was possessing a little girl. Later they discovered that this girl was Damien Darhk's (Neal McDonough) daughter Nora (Courtney Ford). Since then Constantine has fought with the Legends trying to stop it. This week, Constantine is set to re-join to the team when Mallus takes control of Sara Lance (Caity Lotz). He will also appear in the season 3 finale on Monday, April 9.
Per CBR, Warner Brothers TV has announced that Ryan will join the Legends of Tomorrow cast as a series regular *if* the show is renewed for a fourth season. There has been no news regarding this renewal just yet, but looking ahead and casting new characters to join the series is an encouraging sign. Each season of Legends of Tomorrow has been arguably better than the one before it, and it would be silly for The CW to cancel the show just when it's starting to truly hit its stride.
Ryan would be a great addition to the already strong Legends cast, which also recently added Keiynan Lonsdale's Wally West as a series regular. Constantine's charm and snark fits in well with the team and his appearances on the show are always welcome. Plus, as things on Legends vere more and more towards the supernatural, it will come in handy to have some well versed in magic and exorcisms aboard the Waverider.
One of the strongest parts of Legends of Tomorrow is the show's ability to take the forgotten characters from other Arrowverse shows and giving them a place to shine. Sara Lance, Ray Palmer (Brandon Routh), Martin Stein (Victor Garber), Mick Rory (Dominic Purcell) and now Wally West have all been given new life on Legends. It will be great to see the same happen for Constantine, who is a fan favorite for many despite the lack of success with his own show. Hopefully Legends will be renewed so fans have another season of wacky time traveling adventures with this ratag group of heroes.
Legends of Tomorrow continues tonight with 'Neuromancing the Stone' at 8 pm EST on The CW.
