Mum, I’m Alien Pregnant (2026) – As Unique and Quirky as Its Title

Mum, I’m Alien Pregnant is one of those titles that inadvertently makes a huge uphill climb for the film it belongs to. Not because you expect it to be bad necessarily, but rather the film has to live up to the eccentricity of it. It’s an impossible task, but Mum, I’m Alien Pregnant gives it a damn good go. Pregnancy-focused horror is hardly an unexplored avenue in cinema. From classics such as Rosemary’s Baby, to a resurgence in the theme with Immaculate and The First Omen, it’s been mined frequently over the years. Mum, I’m Alien Pregnant can hardly be called a horror, but it’s certainly exploring relevant ideas like those films, albeit in a very different presentation. 

As the word ‘alien’ would imply, this has trappings of sci-fi throughout, as a young woman is unwittingly impregnated by a man whose DNA is clearly not fully human (and I’m not explaining in what area, you can work that out for yourself), and deals with garish and odd symptoms that play on pregnancy stereotypes in gross and darkly comedic ways. Mum, I’m Alien Pregnant certainly commits to the bit when it comes to grotesquerie: emetophobes may not find the image of Hannah Lynch’s Mary vomiting blue stuff everywhere particularly pleasing. Having said that, the dry comedy and the mundanity of everyone’s reactions to it makes it palatable.

Lynch’s main performance is great. She’s carefree without being unlikable, and her nonchalant attitude is matched only by the supporting cast. While Mary is facing a very odd predicament, the reactions from her mum and neighbour would suggest that this is just a normal pregnancy. They’re far from disinterested, but the comedy of them not knowing how they react to this situation is mostly on-point.

The other noteworthy performance is from Arlo Green as the unwilling and hapless father. Once again, the film manages to strike just the right balance here – a character like this, a socially awkward and clumsy young man protected by his mother, could invoke a lot of negative stereotypes and come across as distasteful. While there’s still a lot of comedy at his expense, Green plays him with an endearing sensibility that is enough to make it work. There’s a lot of tension between him and Mary (understandable, after all, she is now alien pregnant), and the cold and uneasy interplay they have throughout keeps the film’s pace going at a good rate.

However, as I said before, this does what all the best pregnancy-related fiction does. It’s actually ‘about something.’ A common theme in films like this is female bodily autonomy – this was especially discussed with Immaculate and The First Omen, which were being developed in the wake of the repeal of Roe v Wade in the United States. Whether they were a deliberate attempt to comment on that is debatable, but the timing felt alarmingly prescient. Mum, I’m Alien Pregnant is being made in a world that is still clearly dealing with the aftershocks of that decision, and while abortion laws in Australia are considerably less restrictive, the filmmakers (collectively known as Thunderlips) clearly have those social issues on their mind.

The film also takes the pregnancy theme down another route, and turns it into a coming-of-age story for Hannah Lynch’s main character. She’s much older than the usual coming-of-age protagonist is, but she’s still living with her mum and is unemployed, barely getting out of bed, and generally drifting aimlessly through her day. The film never once says that the pregnancy is her fault, which of course would be wrong, but it’s a chance for her to reflect on who she is and what she’s doing with her life. Not to mention the sheer uselessness of the distant father, who has no idea what he’s let himself in for and proves to be completely ineffective in the incredibly stressful situations Mary finds herself in. The theme of autonomy is always going to be there in something like this, it’s only natural. But given the urban setting, making a tale about parental responsibility and learning to grow makes sense, and it executes it with aplomb.

Mum, I’m Alien Pregnant won’t be to everyone’s taste. Not to mention it’s the last film title you’d want to mention out of context in a conversation. But as an offbeat comedy laced with dry deadpan wit, and an interesting commentary on themes of maturity and responsibility, it makes for an off-kilter but suitable watch.
