You’re three months late and you swear you haven’t been touched. The doctor slides the ultrasound wand across your belly, and the screen shows — that is not a baby. That’s a baby with too many tentacles.
You laugh, because what else are you going to do, cry in a paper gown?
Welcome to Mary’s Tuesday, horror lovers. Turn off the lights and call your mom — you’re going to want backup.

The news, fiends: the official trailer for Mum, I’m Alien Pregnant dropped today, and the New Zealand body-horror comedy hits digital on October 27 — just in time to make your Halloween plans deeply weird.
The premise is exactly as unhinged as the title promises. Mary is a messy millennial underachiever who accidentally becomes alien-pregnant, and between the skeptical doctors, a useless baby daddy, and an oversharing mother, she’s got to survive the pregnancy and reclaim her life. Birthing pods. Horny tentacles. Bodily fluids. All of it.
This one comes with a pedigree, too. New Zealand doesn’t miss with horror comedies — Peter Jackson built the whole subgenre with Dead Alive and Bad Taste, and the lineage runs straight through What We Do in the Shadows. Mum, I’m Alien Pregnant is the feature debut of filmmaking duo THUNDERLIPS, expanding their 2024 short Help, I’m Alien Pregnant, with Hannah Lynch reprising her role as Mary.
Full disclosure, up front: Harper hasn’t screened this one yet — it premiered at Sundance in January, and the rest of us have been waiting with the general public. But the early numbers are gnarly in the best way: 94% fresh on Rotten Tomatoes. Bloody Disgusting’s Meagan Navarro caught it at Sundance and praised Lynch as “a fiery lead,” noting the film makes sure “there’s no shortage of gross-out gags, birthing pods, horny tentacles, and bodily fluids to showcase just how gnarly pregnancy really is.” RogerEbert.com’s Robert Daniels was more mixed, calling it a thin film that survives on energy and humour. Pregnancy horror meets pregnancy comedy, and neither flinches.
Trivia & Facts
- The feature expands THUNDERLIPS’ 2024 short film Help, I’m Alien Pregnant — same duo, same star, bigger budget, bigger tentacles.
- It marks the feature directorial debut of New Zealand filmmaking duo THUNDERLIPS.
- The film premiered at the 2026 Sundance Film Festival, where it scored its 94% Rotten Tomatoes rating from the first wave of festival reviews.
- Co-star Yvette Parsons comes from What We Do in the Shadows — because of course New Zealand horror comedies share a bloodline.
- Co-star Jackie van Beek co-created the Australian version of The Office, which is the funniest possible credit to bring to an alien pregnancy movie.
Harper’s Extras
- If you somehow haven’t seen What We Do in the Shadows yet, remedy that immediately — it’s essential Kiwi horror-comedy canon.
- For the pure gross-out end of the spectrum, revisit Deathgasm — New Zealand’s earlier entry in the “metal and monsters” hall of fame. And for the body-horror gold standard, revisit The Fly (1986).
- Housebound is the quieter, meaner New Zealand horror-comedy that proves the country’s range.
