Superman & Lois: the TV series, its 4 seasons, its cast and its ending explained

From a crossover to a family drama

Tyler Hoechlin did not start out in Superman & Lois. He first puts on the cape in 2016 in Supergirl, as a guest, then returns regularly. Elizabeth Tulloch, for her part, appears as Lois Lane in the Elseworlds crossover in December 2018. The pairing lands well, and The CW orders a series built around them — a rare case of supporting characters promoted to leads. The actor's career and that of his co-star shed light on that rise.

Todd Helbing and Greg Berlanti choose an angle television had never really attempted. No origin story: when the series opens, Clark Kent has been Superman for years, he is married to Lois, and they have two fifteen-year-old sons, Jonathan and Jordan. Martha Kent's death brings them back to Smallville, and the series becomes as much a rural family drama as a superhero show. It is the exact opposite of what the series that told Clark's youth proposed, and an extension of what the romantic sitcom of the 1990s had attempted before it.

That choice has a direct consequence on the writing: the stakes are almost never “can Superman win?” but “what does the father pay for what the hero gains?”. The sons, meanwhile, gradually discover their Kryptonian inheritance — a device that brings the series close to the modern comics centred on the elder son who becomes a hero in turn.

The full cast

The cast stayed remarkably stable across four seasons, with one exception: the role of Jonathan Kent changes actor between season 2 and season 3.

Two names deserve a detour. Lana Lang, married here and a mother, is no longer the youthful love but the childhood friend who stayed in town — an adult rereading of the character. And John Henry Irons, alias Steel, arrives from a parallel Earth where Superman went wrong: the series thus picks up the blacksmith who took over in the comics. Michael Cudlitz, finally, appears only at the very end of season 3: his Lex Luthor is a man out of prison with a single idea in his head, and he becomes the engine of season 4. His version differs sharply from the one in the 2025 film.

Season 1: the return to Smallville

Fifteen episodes, from 23 February to 17 August 2021. The pilot buries Martha Kent and settles the family on the farm. The twins discover their father's double life; Jordan, the more withdrawn one, turns out to have powers, while Jonathan, the athlete, has none.

The antagonist is Morgan Edge, a press magnate buying up Smallville piece by piece. The series reveals that his real name is Tal-Rho and that he is Clark's Kryptonian half-brother: their mother Lara sent two sons to Earth. Edge transfers Kryptonian consciousnesses into human bodies to rebuild Krypton — a plot that gives the season its colour, half business thriller, half science fiction.

It is the most praised of the four seasons, carried by cinematic photography rarely seen in a network series and by a pilot many regard as the finest launch of a live-action Superman show.

Season 2: Bizarro and Ally Allston

Fifteen episodes, from 11 January to 28 June 2022. The season introduces an inverted Earth and its warped Superman, the hero's imperfect double, then Ally Allston, guru of a cult promising her followers that they can merge with their counterpart from another world.

It is the most openly fantastical season and also the most debated: the pace grows heavy, the teenage plots take up room. It nevertheless contains the scene that redefines the series' entire framework — the revelation, at the end of the season, that this world is not the Arrowverse. We return to that below.

Season 3: Intergang and Lois's cancer

Thirteen episodes, from 14 March to 27 June 2023. The budget drops, the episode count with it, and the series tightens its focus. The criminal organisation Intergang, led by Bruno Mannheim, serves as the main antagonist, but the arc everyone remembers lies elsewhere.

Lois Lane is diagnosed with stage 3 inflammatory breast cancer and undergoes chemotherapy across the whole season. The series takes its time: the appointments, the hair loss, the exhaustion, the sons' fear, the helplessness of a husband who can lift a building but can do nothing against this. It is the season in which Superman & Lois fully earns its title, and Elizabeth Tulloch's performance is unanimously singled out there. The final episode, “Injustice”, brings Lex Luthor into the story.

Season 4: Doomsday, Luthor and the ending

Only ten episodes, from 7 October to 2 December 2024: The CW had announced as early as 2023 that season 4 would be the last, and the team wrote a conclusion knowing it was one. Lex Luthor drives the season, wielding the creature that killed Superman in the comics, here born from Bizarro's mutation.

In the final episode, “It Went by So Fast”, Luthor unleashes Doomsday on Smallville. Superman carries him into the heart of the sun. Then the episode does what no superhero series had dared on television: it leaves the action behind. A jump of one year, then thirty-two years covered in a few minutes. Superman goes on protecting the world, the twins live their lives, Lois's cancer returns and she dies. Clark, very old, passes in his turn from heart failure and is reunited with Lois.

That ending divided viewers. Yet it closes exactly what the series had opened: a story that did not ask whether Superman could win, but what a whole life costs a man who does not age at the same rate as those he loves.

Why this is not the Arrowverse

It is the most frequently asked question about the series, and the answer changed along the way. At launch, Superman & Lois was meant to take place on Earth-Prime, the unified world born from Crisis on Infinite Earths, alongside The Flash and Batwoman.

The crossovers were cancelled, production was complicated by the pandemic, and the writers settled the matter at the end of season 2: the series takes place on its own Earth. Showrunner Todd Helbing put it plainly — the Superman, the Lois Lane, the Lucy Lane and the John Diggle of the series are doppelgängers of those on Earth-Prime, not the same people. In practical terms, for the viewer: no other series is needed. You can start with episode 1 without having seen a single minute of Arrow, Supergirl or The Flash.

Where to watch the series in France

As of 25 September 2026, all four seasons are offered in France by subscription on Prime Video and HBO Max, as well as on Molotov and SFR Play. They are also available to rent and to buy on Canal VOD, the Apple TV Store and Amazon Video. A French-language version exists for every season.

Netflix does not carry the series in France. Streaming offers change regularly: check availability before subscribing for this show alone.

What the series leaves behind

Superman & Lois closed an era. Its final episode is also the last of The CW's DC era, after ten series and more than forty seasons combined. It leaves three things.

First, proof that a married Superman and father works on screen — something the comics had established as early as the 1996 wedding but that adaptations avoided. Second, photography and action staging that raised the standard for network series. And finally, a treatment of illness that stayed with viewers far beyond the superhero audience.

To place the series among the others, our survey of Superman series puts them all in order, from the 1950s serials to the animated series currently running.

Conclusion

Four seasons, 53 episodes, and a bet paid off: telling Superman through what his life costs rather than what his fists achieve. Superman & Lois lacks the cultural reach of Smallville and the budget of the films, but it did something no other adaptation had attempted: it followed the Man of Steel all the way to the end.

To go further, the story of the couple in the comics illuminates what the series adapts, and the full portrait of Lois Lane shows how far the character has come since 1938.
