Development
At the Television Critics Association press tour in January 2018, The CW president Mark Pedowitz said he was "optimistic" and "confident" about Supergirl and the other Arrowverse shows returning next season, but added that it was too soon to announce anything just yet.[17] On April 2, The CW renewed the series for its fourth season.[18] Robert Rovner and Jessica Queller returned to serve as the season's showrunners without their former co-showrunner Andrew Kreisberg, who was fired during the previous season.[19]
Writing
Following the conclusion of the third season, which closed with a second Kara Danvers born from the aura that escaped during the final battle with Reign being found by Russian soldiers in Siberia, Robert Rovner and Jessica Queller confirmed that the fourth season would be inspired by the comic book mini-series. Queller described the adaptation as "an homage" to the series, which portrays what would have happened if Superman had landed in Russia and became a hero there instead of in America.[20] The story intended to examine the nature-versus-nurture debate, and developed as a "slow-burn" throughout the season.[21]
At San Diego Comic-Con 2018, Rovner and Queller stated that the season would aim to be more "grounded" than previous seasons in order to touch on topical real-world issues.[22] They confirmed that the fourth season would look to refocus on Kara's professional career as a reporter and see her act as a mentor to Cat Grant's former protégé, both at CatCo and as a superhero, paralleling Kara's own journey of coming into her own. The duo added that "This is the season where Kara becomes as much a hero as Supergirl."[23] Teasing the main villain of the season, the producers described Agent Liberty as the leader of "a hate group that supports a human-first world order" and under the guise of a family man, provokes "anti-alien sentiment in the country, echoing the hateful rhetoric we're seeing right now in certain American politics."
Rovner and Queller also announced that the theme of the season would be "What is stronger: hope or fear?" Melissa Benoist commented that, "I think their main premise is that fear itself is a villain, and can hope conquer it? Supergirl stands for hope, so we'll see."[24] Queller concurred, adding that the season would investigate, "How can [Supergirl] be a beacon of hope when she represents what people are afraid of?"
Casting
Main cast members Melissa Benoist, Mehcad Brooks, Chyler Leigh, David Harewood, and Katie McGrath return from previous seasons as Kara Danvers / Kara Zor-El / Supergirl, James Olsen / Guardian, Alex Danvers, J'onn J'onzz / Martian Manhunter, and Lena Luthor, respectively. Benoist also portrays Red Daughter, the clone of Kara.[25] The fourth season is the first not to feature original cast member Jeremy Jordan, who plays Winn Schott. While it was initially announced that he would shift into a recurring capacity for the fourth season,[26] Rovner later said he would not appear until the fifth season.[27] Chris Wood and Odette Annable, who became regulars in the second and third seasons, respectively, too did not reprise their roles as Mon-El and Samantha Arias / Reign, respectively, as regulars in the fourth season.[28] [29] Jesse Rath was promoted to a series regular after previously recurring in the third season as Querl "Brainy" Dox / Brainiac 5.[30] Sam Witwer joined the main cast as Agent Liberty.[31] Nicole Maines and April Parker Jones had been cast as series regulars and would portray Nia Nal / Dreamer and Colonel Lauren Haley, respectively, with the former to become the first transgender superhero on television.[32]
Brent Spiner was originally cast as Vice President Baker in August,[33] but the role was recast later that month with Bruce Boxleitner due to Spiner having "family issues conflicting with the show's production dates".[34] Lex Luthor, Lena's half-brother and the archnemesis of Kara's cousin Superman, was introduced in this season;[35] Jon Cryer, who portrayed Lex's nephew Lenny Luthor in the film , was cast in the role.
Filming
Production for the season began on July 11, 2018, in Vancouver, British Columbia, and concluded in April 2019.[36] [37] Melissa Benoist joined filming following the conclusion of her run on Broadway as the star of on August 4, 2018.[38]
Arrowverse tie-ins
In May 2018, Arrow star Stephen Amell announced at The CW upfronts that the next Arrowverse crossover would feature Batwoman and Gotham City. The crossover "Elseworlds" was a pilot for Batwoman solo series which was launched in October 2019.[39] [40] [41]
Marketing
The main cast of the season as well as executive producers Robert Rovner, Jessica Queller, and Sarah Schechter attended San Diego Comic-Con on July 21, 2018, to promote the season.[42]
Release
Broadcast
In May 2018, it was announced that Supergirl, which had aired on Mondays since its debut, would move to Sundays for its fourth season due to the wrong date due programming expansion to Sunday nights.[43] The season premiered on The CW in the United States on October 14, 2018.[44] The annual crossover episode will swap time-slots with The Flash for that week and will air on Tuesday, December 11.[45]
Home media
The season was released on DVD and Blu-ray on September 17, 2019, with special features including the show's 2018 Comic-Con panel, deleted scenes and a gag reel. The Blu-ray release also included all three episodes of the fifth annual Arrowverse crossover event titled "Elseworlds".[46]
Reception
Critical response
The review aggregation website Rotten Tomatoes reports a 87% approval rating for the fourth season, with an average rating of 7.26/10 based on 7 reviews. The website's critic consensus reads: "Though it's a little tonally inconsistent, Supergirls fourth season still soars thanks to strong, relevant writing brought to life by its charming cast."[47]
Reviewing for Den of Geek, Delia Harrington gave the premiere a rating of 4/5, writing: "The Supergirl season 4 opener sows the seeds of a season's worth of conflict while being a great episode in its own right."[48] IGNs Jesse Schedeen said of the premiere that, "After a disappointing finish to a generally underwhelming Season 3, it's good to see Supergirl quickly bouncing back this week. 'American Alien' sets the stage for a promising conflict to come, introducing memorable new villains and supporting characters and forcing Kara to confront the things she can't control in her city. Supergirl is borrowing several pages from the X-Men playbook, and that's by no means a bad thing." He gave the episode a rating of 8.6/10, concluding that, "Supergirls fourth season is off to a promising start thanks to an eventful and dramatic premiere episode."[49] Overall, he gave 9/10 points to the whole season, stating that "Supergirl's fourth season is undoubtedly the strongest to date, thanks in large part to the concerted effort to make up for the lack of compelling, nuanced villains in year's past. The finale episode ties all those threads together in a satisfying way, wrapping up the shared saga of Red Daughter, Agent Liberty and Lex Luthor while also setting up Lena Luthor to become Kara's greatest and most personal enemy yet."[50] Caroline Siede of The A.V. Club concurred with Schedeen's X-Men comparison, reflecting that over the seasons, "[''Supergirl''] has grown both more explicit and more nuanced in its handling of social and political issues." Siede gave the premiere a "B+" grade, explaining, "I'm tempering my optimism with just a little bit of caution. [...] Supergirl still has plenty of room to grow, but it's nice to see the show get its core ethos so right."[51]
The book Adapting Superman: Essays on the Transmedia Man of Steel includes the chapter "Forging Kryptonite: Lex Luthor's Xenophobia as Societal Fracturing, from Batman v Superman to Supergirl," which analyzes Lex Luthor's actions in Season 4 "as a representation exploring the cultural effects of encroaching xenophobia" from society to the family in the years following the 2016 United States presidential election.[52]
