Lucifer‘s showrunnners are just as curious about Constantine’s (Matt Ryan) previous relationship with Lucifer (Tom Ellis) and Maze (Lesley-Ann Brandt) as you are after Ellis’ cameo in the Arrowverse’s “Crisis on Infinite Earths” crossover.
In The Flash installment of the five-hour CW superhero event, Constantine, John Diggle (David Ramsey), and Mia Smoak (Katherine McNamara) traveled to Earth-666, home of Netflix and WBTV’s Lucifer, because they needed the Devil’s help retrieving Oliver Queen’s soul from Purgatory. During the exchange, which takes place before the events of Lucifer‘s pilot, the fallen angel said he was only helping them because he owed the chain-smoking occult detective for a favor he did for Maze way back when.
Although the Lucifer team did consult on the scene, it was primarily the brain-child of Flash writer and Lucifer fan Lauren Certo, who co-wrote the hour with Sterling Gates — including that line hinting at a previous devil’s bargain between Lucifer, Constantine, and Maze, which got their wheels spinning.
“I have thoughts,” Lucifer co-showrunner Joe Henderson tells EW about that piece of dialogue. “By the way, credit where credit is due: That scene, we only added two things to it. One, I pitched the flirt joke, which Tom surprised the actor who plays Diggle with. I wish we’d been covering his side because you got a great reaction from him. And then the Constantine, Constantyne [bit], that was Tom having heard about the debate from one of our writers. Other than that, that was all them [on The Flash]. And I thought they did such a wonderful job of capturing the voice, knowing how to write Lucifer, because Lauren Certo, [who] watches the show [and] is a fan of it, wrote our Lucifer, which was lovely.”
“I have theories [about Lucifer and Constantine’s past relationship] and we should explore it in the spin-off,” he adds as both him and co-showrunner Ildy Modrovich laugh. And no, there isn’t actually a spin-off in the works.
Henderson went on to reveal that he’s been dreaming of a Lucifer-Arrowverse crossover ever since the conclusion of last year’s Arrowverse event, “Elseworlds.”
“A year ago when they announced ‘Crisis on Infinite Earths,’ I called the executive of DC and I’m like, ‘If there are infinite earths, that means Lucifer‘s on one of them. And I don’t know if they’d already thought of it. I still haven’t actually asked Marc Guggenheim. I’ve been meaning to. I don’t know what was the chicken and the egg, but all I know is like that has been something that I’ve been wanting to do ever since I heard it happened and I can’t believe we actually did it. It’s the coolest thing,” he says.
“Joe fought very hard for that one,” says Modrovich, with Henderson adding, “It was a tricky thing to do, but it’s just awesome. When Tom and Matt Ryan got together, like they were outside their stage and they’re both like talking about the characters and what they could do, and I’m just like, ‘My mind is blowing cause Lucifer and Constantine are brainstorming a scene together and having the time of their lives.’ It was just delightful.”
Lucifer is currently in the middle of production on its final season, which will be split into two parts and is expected in 2020.
“Crisis on Infinite Earths” resumes Jan. 14, 2020 with Arrow at 8 p.m. and DC’s Legends of Tomorrow at 9 p.m. on The CW.
