In 2 Weeks, James Gunn's DCU Will Officially Release The Missing Superman Crossover

Published Jun 9, 2026, 7:30 PM EDT

Supergirl and Superman team up quite often in comics, shows, and animated movies. The CW's Supergirl show, for example, served as the first appearance of Tyler Hoechlin's Clark Kent. They haven't, however, ever had a proper team-up in a theatrically-released movie. That is, until Supergirl changes that fact and gives Kara and Clark their first proper crossover on June 26.

Supergirl Will Unite Kara & Clark Properly For The First Time In Theaters

When Supergirl premieres on June 26, it will be the first theatrical movie to give viewers a real crossover between Supergirl and Superman. The ending of Superman 2025 already included a cameo from Kara Zor-El that teased this upcoming film, but we also know that Clark will be returning. Some of the trailers for Supergirl have highlighted interactions between Kara and Clark, including one very important moment.

It now seems that Supergirl is going to begin with the moment when Kara landed on Earth and discovered that Clark had arrived some decades before her, thanks to a clip showing David Corenswet's Superman in Supergirl. In the clip, Clark and Kara have a difficult time speaking, as Kara only speaks Kryptonian, and it ends just as Kara is about to receive her powers from Earth's yellow sun.

Previously, since Supergirl is an adaptation of the "Woman of Tomorrow" comics, it was assumed that Kara would mostly be on her own in the film. Given that clip of Kara and Clark meeting, however, it now seems that Supergirl is something of an origin story for Kara. It could easily include footage of Kara and Clark working together as superheroes before she sets off on her journey across the galaxy. In short, Supergirl is shaping up to be the Supergirl/Superman team-up fans have been wanting to see for decades.

Supergirl Met Superman In The Flash, But It Wasn't What Fans Wanted

While Supergirl will be the first time Kara and Clark properly team up in a theatrical live-action movie, it won't be the first time it has ever happened. Technically, Supergirl did meet a version of Superman in 2023's The Flash. In that DCEU movie, a CGI model based on Christopher Reeve's Superman and Helen Slater's Supergirl briefly shared a cameo appearance. That marked the first time the characters had appeared together in a theatrical live-action movie, as Reeve and Slater were never in the same movie together back in the 1980s.

That cameo appearance in The Flash, however, was very far from a proper crossover between Supergirl and Superman. Firstly, the characters were only on screen together for a few seconds, and all they did was float in the air near each other. Secondly, they were entirely CGI, a decision that was controversial in itself due to using the likeness of a dead actor like Reeve. It was altogether underwhelming and not at all what Supergirl fans wanted the first theatrical meeting of the characters to be.

Supergirl, in stark contrast to The Flash, will have Kara and Clark interact while being portrayed as real living actors, share an actual frame, and presumably even fly around together. There's even potential for a recap of their early days together at the start of the film. Finally, after decades of waiting, James Gunn's DCU is finally letting Supergirl bring Superman and Supergirl together on the big screen.
