Caution: Spoilers for Peacemaker season 2, episode 6 ahead!
At the start of the month, James Gunn delighted DC enthusiasts by revealing that a sequel to Superman called Man of Tomorrow is in production, with a release date set for July 2027. This upcoming film features David Corenswet as Clark Kent/Superman and Nicholas Hoult as Lex Luthor, who will unite to confront a mutual adversary.
The exact nature of the threat that this unusual pair will tackle remains largely under wraps, although speculation suggests Brainiac might be the antagonist in Man of Tomorrow. Intriguingly, Hoult’s unexpected appearance in Gunn’s DC series, Peacemaker, gives a glimpse into the trajectory of Lex Luthor’s character leading into the Superman sequel.
In the sixth episode of Peacemaker season two, Lex finds himself in Belle Reve Penitentiary following the events of the inaugural DC Universe movie. He negotiates a transfer to a non-metahuman facility in exchange for his assistance to Rick Flag Sr. in locating Peacemaker’s quantum unfolding chamber. This connection with ARGUS in the comics sets the stage for Lex’s involvement in the DCU moving forward.
Gunn recently elaborated on Hoult’s cameo in Peacemaker, stating that while audiences will “not necessarily see Nick, his agreement plays a crucial role not just in the current season but also in Man of Tomorrow.” He further discussed his approach to integrating the DC Films and series:
“It’s essential that each project can stand alone. I don’t want fans to feel obligated to watch Peacemaker if they prefer Superman, and vice versa. There are connections, but when I helm Man of Tomorrow, I ensure viewers can jump straight in and grasp the plot without needing to watch Peacemaker. Superman differs slightly as it is a sequel.”
Implications of James Gunn’s Remarks on Lex Luthor for Man of Tomorrow
Gunn’s decision to intertwine Lex Luthor with ARGUS in Peacemaker might appear minor now, but it has significant implications for the DCU. Lex’s involvement with ARGUS traditionally leads to a collaboration known as Project Cadmus, which is dedicated to studying metahuman genetics. Notably, Cadmus Labs is credited with creating Superboy/Conner Kent.
This tease suggests a potential Project Cadmus storyline in the DCU’s future, although it might be some time before it develops. For Man of Tomorrow, it implies several things.
Most crucially, Lex is cooperating with the government. Although he currently only requested a transfer, continued collaboration with ARGUS could lead to a reduction in his 265-year sentence. Moreover, as anti-metahuman sentiment persists in the DCU, Lex might gradually regain his influence to oppose figures like Superman and the Justice Gang.
This government tie-in could pave the way for Superboy’s introduction and possibly set Lex on a path to redemption in the public eye, potentially leading to a presidential run as seen in the comics. Naturally, these developments depend on how Lex’s storyline evolves in Man of Tomorrow.
For now, it seems Lex’s favor with ARGUS might result in him and Superman either voluntarily collaborating or being coerced to work together by the agency, especially if they face an extraterrestrial threat in Man of Tomorrow. While Peacemaker provides context for Lex’s narrative, Gunn’s statements suggest these connections may not be deeply explored in Man of Tomorrow or will be sufficiently explained within the movie.
Analyzing James Gunn’s Comments on Lex Luthor
Gunn’s remarks open various potential narrative paths for Lex Luthor within the DCU. The mention of Cadmus is significant, as it has been a prominent element in Lex’s storylines across multiple media, including Smallville and Young Justice. Even if it’s a long-term plan, this major cameo sets up Lex’s arc in Man of Tomorrow in an intriguing and unexpected manner.
