If you’ve somehow missed the wonderfully weird world of Resident Alien, where have you been hiding? Probably not in a cabin in Colorado pretending to be a doctor while secretly plotting humanity’s destruction.
Part comedy, part sci-fi mystery, and part heartfelt small-town drama, Resident Alien has quietly become one of the most loved cult TV shows of recent years. Starring the endlessly talented Alan Tudyk as an alien attempting to blend into human society, the series delivers laugh-out-loud moments, emotional storylines, and enough awkward encounters to make anyone grateful they’re not secretly an extraterrestrial.
Whether you’re a long-time fan or have just discovered the show, here are some fascinating Resident Alien facts that you probably didn’t know.
1. Resident Alien Is Based on a Comic Book
Before Harry Vanderspeigle arrived on our screens, he first appeared in the Resident Alien comic series created by Peter Hogan and Steve Parkhouse.
The television adaptation follows many of the same core ideas but expands the universe considerably, adding new characters, storylines, and plenty of extra chaos.
2. Alan Tudyk Almost Didn’t Take the Role
It’s difficult to imagine anyone else playing Harry.
Thankfully, Alan Tudyk was instantly intrigued by the script. The chance to play an alien trying to understand human behaviour gave him endless opportunities for physical comedy.
The result?
One of the funniest TV performances in years.
3. Harry’s Walk Was Carefully Created
That wonderfully awkward Harry walk wasn’t accidental.
Tudyk spent time developing a unique physical movement style to make Harry appear slightly “off” without becoming cartoonish.
Now, it is one of the character’s most recognisable traits.
4. The Show Was Filmed in Canada
While Resident Alien takes place in the fictional Colorado town of Patience, much of the series was filmed in beautiful British Columbia, Canada.
The stunning mountain scenery helps create the perfect small-town atmosphere.
5. Harry’s Human Reactions Are Based on Observation
One of the funniest parts of Resident Alien is watching Harry attempt to copy human emotions.
Tudyk has spoken about observing real-life behaviours and exaggerating them slightly to make Harry’s attempts to fit in feel believable but hilariously uncomfortable.
6. The Cast Didn’t Always Know What Harry Would Do
Apparently, Tudyk sometimes surprised his fellow actors with unexpected reactions and physical comedy.
Many of the funniest scenes show the cast trying not to laugh, with their genuine reactions.
7. The Octopus Became a Fan Favourite
Let’s talk about the octopus.
Yes, that octopus.
Few television shows could make viewers emotionally invested in conversations between an alien doctor and a sea creature, yet Resident Alien somehow managed it.
Fans quickly adopted the octopus as one of the show’s most beloved characters.
8. The Show Balances Comedy and Heartbreak Surprisingly Well
At first glance, Resident Alien looks like a straightforward comedy.
Then suddenly you’re crying.
The series regularly explores grief, loneliness, identity, friendship, and belonging, while also delivering jokes about aliens misunderstanding basic human behaviour.
It’s a strange combination that somehow works perfectly.
9. Harry Was Originally Meant to Be Much Darker
The comic version of Harry can be more mysterious and serious.
The television adaptation leans heavily into comedy, largely thanks to Tudyk’s performance.
Many fans believe his performance helped the show reach a wider audience.
10. Alan Tudyk Is a Disney Legend
Long before Resident Alien, Alan Tudyk built an incredible career.
You may recognise him from:
- Rogue One
- Moana
- Frozen
- Wreck-It Ralph
- Firefly
At this point, he’s practically Disney royalty.
11. The Kids Steal Almost Every Scene
One of the smartest decisions Resident Alien made was giving the children major roles.
The relationship between Harry, Max, and Sahar provides some of the funniest and most chaotic moments in the series.
They’re also among the few people capable of seeing straight through Harry’s terrible attempts at being normal.
12. Fans Love the Small-Town Setting
Patience may be fictional, but viewers adore the sense of community.
Unlike many sci-fi shows focused on massive intergalactic conflicts, Resident Alien often feels cosy, even when humanity’s fate is at stake.
13. Harry Was Never Supposed to Be This Likeable
The original premise involved an alien whose mission wasn’t exactly friendly.
Over time, Harry’s relationships with the townspeople slowly changed him.
Watching him become more human remains one of the show’s strongest storylines.
14. The Show Has Built a Huge Cult Following
While it may not receive the same attention as some streaming giants, Resident Alien has developed an incredibly loyal fan base.
Many viewers discovered the show through word of mouth and quickly became obsessed.
If you’ve ever recommended it to friends, you’re definitely not alone.
15. Nobody Expected It to Become Such a Hit
When Resident Alien first launched, few predicted it would become one of television’s most beloved sci-fi comedies.
Yet here we are, several seasons later, still laughing at Harry’s confusion over basic human interactions.
That’s what makes the show so special.
Why We Can’t Stop Watching Resident Alien
At its core, Resident Alien isn’t really about aliens.
It’s about what it means to be human.
Harry spends the series trying to understand friendship, love, grief, loyalty, and connection. Ironically, his outsider perspective often reveals truths about humanity that we overlook ourselves.
Add brilliant writing, fantastic performances, and a healthy dose of weirdness, and you’ve got one of the most entertaining TV shows around.
Now, if you’ll excuse me, I’m off to practise Harry’s awkward walk and to question whether that suspiciously quiet neighbour might actually be from another planet.
