The marketing campaign for the upcoming Supergirl film finally revealed the green sun, which will significantly impact the plot and Supergirl's abilities. With the premiere of Supergirl just around the corner, the film's marketing campaign is in the final stretch. Recent trailers, clips, and other materials continue to introduce fans to new elements of the project just before its release, and the latest has finally given everyone their first glimpse of the kryptonite sun that Kara Zor-El will have to battle.
Warner Bros.' official Argentine YouTube channel recently released a 75-second video about the making of Supergirl, specifically how the film drew inspiration from the Woman of Tomorrow comic book. The video featured comparisons of stills from the film and the comic book fragments that served as inspiration for them or were directly incorporated into the film.
Specifically, at the 1:00 mark of the video, Warner Bros. showed a comparison shot featuring Millie Alcock's Kara Zor-El and Eve Ridley's Ruthie Knoll on one side, and the comic book version of Kara and Ruthie on the other. Notably, they are on a planet with a green sun on the horizon, and Kara appears to be lying on the ground, weakened.
In this image, DC Studios revealed for the first time its version of the green sun from DC Comics, which essentially acts like kryptonite, greatly weakening and harming Kryptonians like Supergirl and Superman.
In a still from the film, Kara appears too weak to even rise from the ground, as the sun drains her strength and physical energy.
As mentioned, this part of the story is a direct copy of the Woman of Tomorrow comics, as in that series, Ruthie and Kara find themselves on the planet Barenton, which essentially serves as a prison for Supergirl. The green sun is essentially a giant ball of kryptonite, meaning it severely drains her powers.
The comics explain that Barenton was created specifically as a trap for Superman (who would appear in the series "Supergirl"), which is why Kara knew about it. When the Man of Steel found himself trapped there, he simply waited until sunset to escape the planet.
However, he only had to wait 45 minutes for sunset, so he was very lucky. Ruthie and Supergirl still had 10 hours before sunset, which meant they had a long way to go.
It's also worth noting that in the comics, Barenton was teeming with ferocious monsters. Since the green sun had weakened and left the Kryptonians vulnerable, the monsters were there to essentially finish off Superman and Supergirl.
It's unclear how closely the film will follow the comics. For example, Supergirl and Ruthie may not be trapped for 10 hours like in the comics, and the monsters may not play as significant a role.
However, a recent making-of documentary has proven that they will visit Barenton (or at least another planet directly inspired by Barenton), and that it will have a green sun that will greatly weaken Kara.
Other promotional materials for the film depict Kara in a weakened state. For example, trailers featured shots of Kara's eyes looking tired, her skin pale, and dark veins visible through it.
These shots were likely filmed on the same planet and show Kara in a weakened state due to exposure to a kryptonite sun. Judging by the film's promotional materials, the kryptonite sun and a weakened Kara will play a significant role in the film and may take up a significant portion of screen time.

Will Supergirl adopt other elements of the Woman of Tomorrow series?
The recently released film about Supergirl's comic book inspiration, "Woman of Tomorrow," suggests it will directly adapt several scenes from the comic, in some cases seemingly word for word. This makes sense, as the film is based entirely on the comic book series, but it also revealed that in some ways it will feel more like a live-action adaptation of the comics.
This means that the rest of the film will likely be similar to the Barenton scene as well, as it will include dialogue, important moments, and even recurring camera angles and shots from the comics.
The Supergirl series was originally titled Supergirl: Woman of Tomorrow, but DC dropped the "Woman of Tomorrow" part from the title (likely due to the Superman sequel being called Man of Tomorrow), so it's no surprise that it will follow the comic book storyline and details closely.
