The series stars Tyler Hoechlin and Elizabeth Tulloch as the titular characters, Clark Kent / Superman, a costumed superhero, and his wife, Lois Lane, as they struggle with the trials and tribulations of being parents, while facing the mysterious Captain Luthor and Morgan Edge.

Hoechlin and Tulloch are joined by main cast members Jordan Elsass, Alex Garfin, Erik Valdez, Inde Navarrette, Wolé Parks, Adam Rayner, Dylan Walsh, and Emmanuelle Chriqui.

Superman & Lois was picked for a full season by The CW in January 2020 and filming took place primarily in Surrey, British Columbia.

The pilot episode was watched by 1.75 million viewers, the second-best premiere of any CW series since the debut of Batwoman in October 2019.

Announced in October 2019, the executive producers for Superman & Lois were named as Todd Helbing, Greg Berlanti, Sarah Schecter and Geoff Johns around the same time.

[16] The first season of the series was officially ordered by January 14, 2020, by The CW[29] and was originally supposed to consist of 13 episodes.

[36] In November 2020, series writer Nadria Trucker was fired after "pushing back on racist and sexist storylines" and working on all 15 episodes of the first season.

[37][38][39] In October 2019, along with the series' announcement before it was officially ordered, Tyler Hoechlin and Elizabeth Tulloch were set to reprise their roles of Clark Kent and Lois Lane from Supergirl.

[21] In October 2020, Sofia Hasmik and Stacey Farber were cast in the recurring roles of Chrissy Beppo and Leslie Larr, respectively.

[26][25] In December 2020, David Ramsey was revealed to be reprising his Arrow role of John Diggle in addition to directing at least one episode in the series.

The website's critical consensus reads, "Though it may be a bit too grounded for some viewers, Superman & Lois draws strength from unexpected places – without skimping on the action – to carve its own path in a crowded superhero universe.

The idea of Lois and Clark being parents isn't entirely new, as Jon Kent has become a mainstay of the Superman comics since 2015.
