Supergirl Adds Seth Rogen — But Don’t Expect A Big Role
Krypto? Think again. A more credible rumor pegs Seth Rogen for a different Supergirl role in Craig Gillespie and Milly Alcock’s DCU film, via insider DanielRPK on X.
File this under rumors that actually make sense: Seth Rogen apparently popped up in Supergirl, but not the way you might think.
The new chatter: not Krypto, a space bus
After a round of whispers that Seth Rogen was voicing Krypto in Craig Gillespie's Supergirl (starring Milly Alcock), a new rumor sounds a lot more plausible. Per longtime scooper DanielRPK on X — echoed by the Everything_DCU account on December 23, 2025 — Rogen shows up briefly as a small alien who helps run a space bus.
"a small alien guy who helps run a space bus"
Yes, a space bus. Weird, kind of delightful, and honestly the right level of silly for a cameo. Fans are already jokingly calling the character 'Paul,' though that name doesn't come from any official place.
Why this tracks better than the Krypto thing
The Krypto rumor started because early test screenings reportedly revealed Rogen had a voice role in the movie, and that got spun into him voicing Supergirl's super-dog (ComicBookMovie.com helped push that idea). The problem: in the comic the film is pulling from — Tom King and Bilquis Evely's 'Supergirl: Woman of Tomorrow' — Krypto does not talk. He's a loyal, superpowered dog. No dialogue, no telepathy, no handy translation device. Some older comics gave Krypto human-level smarts and thought bubbles, but this specific version sticks to dog rules.
So yeah, having an Emmy-winning comedian voice an animal that doesn't speak was always a stretch. A quick-hit alien cameo? That makes sense.
Tone check: where comedy fits
Supergirl, as this movie tells it, is grim: Kara is injured, adrift, and basically forces her life back on track. James Gunn will surely sprinkle in some jokes, but the spine is heavy. Dropping Rogen in as a blink-and-you-smile space-bus alien is exactly the kind of pressure release that doesn't derail the mood.

If the space-bus bit is real, I'm into it. A quick Rogen cameo feels like the right amount of seasoning. How about you — does 'Seth Rogen as tiny alien transit staffer' click, or do you still want to hear that laugh coming out of Krypto?
