Shudder has released the second trailer for Mum, I’m Alien Pregnant, the New Zealand horror-comedy that premiered in the Midnight section of the 2026 Sundance Film Festival. FirstShowing. net reported the announcement on September 7, 2026, noting that the film is hitting theaters in New Zealand starting this week.
The film is the first feature from the New Zealand filmmaking duo Thunderlips, previously known for eccentric music videos and short films. The story follows Mary, a slacker living with her mother in New Zealand suburbia, who accidentally becomes alien-pregnant after an awkward sexual encounter with a strange new neighbor. She must navigate dismissive doctors, a useless baby-daddy, and a host of physical side effects to survive and reclaim her life.
Hannah Lynch stars as Mary, with Yvette Parsons as her overbearing mother Cynthia, Arlo Green as the hapless half-alien baby-daddy Boo, and Jackie van Beek as Ann. The film is described as a classic Kiwi gross-out take on pregnancy and parenthood, blending body horror with comedy. It concludes with a slimy climax that reconciles Mary’s changing body, the unborn alien, and her mother.
Produced by Ilai Amar, Morgan Leigh Stewart, and Alix Whittaker, the film remains without a set US release date as of the latest reporting.
