'Supergirl' will reveal more about DCU's Krypton House of El

It’s very true to the graphic novel that it’s based on, Woman of Tomorrow. Which is great. I’m thrilled to be sort of the next piece of telling the story of Krypton and sort of further clarifying what the House of El is all about.

In the comics, Supergirl’s father, Zor-El, is the brother of Jor-El, Superman’s dad. He was one of the only people who believed his brother when he said that Krypton was doomed. He and his family survived Krypton’s initial destruction by inhabiting a separated chunk of the planet, known as Argo. But eventually, the citizens of Argo succumbed to Kryptonite poisoning. That’s when they sent their teenage daughter, Kara, to Earth. On Earth, she became Supergirl, working together with her cousin Superman. She never knew her uncle Jor-El, but if her species were genocidal conquerors, she would probably know.

Based on Krumholtz’s comments, maybe all Kryptonians are not alike. Perhaps Jor-El was the black sheep of the House of El. Or maybe his brother Zor was a pacifist, and didn’t align with the rest of his culture. Although the revelation about Jor-El in Superman was a shock to many, there are canon examples of Kal-El’s parents being less than great. In the Man of Steel comic reboot of the ’80s, Lara asks Jor-El if their son will grow up to conquer Earth, and mold humans to “proper Kryptonian ways.” Jor-El seems less enthused about the idea, but not outright disgusted. Smallville also suggested Jor-El wanted his son to take over the Earth. One way or another, Supergirl will definitely shed more light on the DCU version of Krypton.

Supergirl , directed by Craig Gillespie, hits theaters on June 26, 2026.
