Until there's official confirmation from Warner Bros. that Constantine 2 is a go, everything out there should be considered speculation. However, there are certainly plenty of reasons to examine an Instagram post Peter Stormare (who plays Lucifer in Constantine) made back in November of 2020. 

The image consists of a Total Nerd Photoshop of the actor as Lucifer with the caption, "In Constantine, Peter Stormare plays one of the best versions of Satan in film history." Stormare goes on to add his own message, which states, "Sequel In The Works." This sent his fans into a tizzy, with dozens of people commenting, expressing their gratitude, and asking if the news is real. Honestly, we're not quite sure what to make of this. 

It's bizarre an actor would make such an announcement without the studio backing it up in any way, but by all accounts, it isn't just Stormare's followers who'd love to take another crack at this philosophical action franchise. Back in the summer of 2020, producer Akiva Goldsman was on a ComicCon@Home panel where he described a potential scene that could've been included in a follow-up, stating, "[John] wakes up in a cell, he has to identify a prisoner. Remember? It was [screenwriter Frank Cabello's] idea. [The prisoner] was Jesus. He comes up and he's in New York. Just ... yeah we talked about a few scenes" (via Collider).

Director Francis Lawrence also expressed how Constantine is more popular now than in 2005, saying, "People have sort of discovered it recently, weirdly. It's always had its cult fanbase, which is great. But I think people have discovered it in a new way. So I think we always loved it more than the studios did." With renewed interest, perhaps a sequel could be in the cards.
