He didn't need a lot of lines. Honestly, he barely needed to blink. When Brian Thompson first appeared on screen in the 1995 episode "Colony," he didn't just play a villain; he became the physical embodiment of a conspiracy that was suddenly way too big for Mulder and Scully to handle.
Before Thompson’s Alien Bounty Hunter showed up, the "aliens" in the show were mostly lights in the sky or blurry figures in the woods. Then comes this guy. He’s massive, he’s wearing a nondescript trench coat, and he has a jawline that looks like it was chiseled out of granite. He felt real. He felt dangerous. And most importantly, he felt utterly indifferent to human life.
The Face of the Conspiracy
Brian Thompson was already a "that guy" in Hollywood long before Chris Carter called him. You've probably seen him as the punk who gets his clothes stolen by Arnie in The Terminator or the terrifying Night Slasher in Cobra. But Brian Thompson in The X-Files was something different.
David Duchovny actually pitched the idea for the character. He wanted a "bounty hunter" from space, someone who wasn't just a monster but a professional. A cleaner. Thompson brought this weird, understated energy to the role. He wasn't screaming or snarling. He was just... there. Waiting.

Why he worked so well:
- Physicality: Standing at 6'3" with an incredibly unique facial structure, he didn't need makeup to look "otherworldly."
- The Stiletto: That retractable ice-pick-looking weapon at the base of his neck? Pure nightmare fuel.
- The Green Blood: The moment we saw that toxic green ooze instead of red blood, the stakes of the show shifted permanently.
Not Just Another Monster of the Week
Usually, The X-Files monsters died at the end of the hour. Not this guy. Thompson’s Bounty Hunter became a recurring nightmare that bridged the gap between the "monster of the week" episodes and the heavy mythology. He was the one who enforced the "Purity" project. He was the one the Syndicate feared.
Remember the episode "The Unnatural"? It’s widely considered one of the best in the series. It’s a 1940s period piece about an alien who just wants to play baseball. Thompson shows up as the Bounty Hunter, and suddenly this whimsical, heart-wrenching story turns into a cold-blooded execution. It’s a testament to his screen presence that he could walk into a sunny baseball field and make the temperature feel like it dropped twenty degrees.
The "Discount Arnie" Misconception
A lot of people back in the 90s called him a "budget Schwarzenegger." That’s kinda disrespectful, honestly. Thompson is a classically trained actor with a Master of Fine Arts from UC Irvine. He wasn't just a bodybuilder who stumbled onto a set.

If you watch his performance closely, he’s doing a lot of micro-expressions. He’s playing a shape-shifter who has seen thousands of years of galactic history and finds human struggle slightly boring. He’s not a "tough guy"—he’s a cosmic janitor.
The Myth of the "Easy" Role
You’d think playing a stoic alien would be easy, but Thompson has talked in interviews about how physically demanding the role was. Vancouver was cold. The sets were wet. He often had to stand perfectly still in freezing rain while the crew set up shots. He also had to deal with the "green blood" effects, which were basically just thick, messy syrups that got everywhere.
Beyond the Trench Coat
While we all know him for the Bounty Hunter, Thompson’s career is a roadmap of sci-fi history. He’s one of the few actors to appear in almost every Star Trek spin-off (The Next Generation, Deep Space Nine, Voyager, and Enterprise). He’s played Klingons, Romulans, and Jem'Hadar.

But it’s the Alien Bounty Hunter that sticks. Maybe it’s because he represented the moment The X-Files stopped being a show about urban legends and started being a show about a silent, inevitable invasion.
What You Should Do Next
If you’re looking to revisit Brian Thompson’s best work in the series, don't just binge the whole thing. Focus on the "Colony" and "End Game" two-parter in Season 2. That’s where the character is at his most mysterious. Then, jump to Season 6’s "The Unnatural" to see how he could play the character with a slightly different, more philosophical edge.
Keep an eye out for his "stiletto" prop in those scenes—Thompson has mentioned in fan retrospectives how tricky that thing was to operate on camera without looking goofy. It’s those little details that made the character a legend.
Check out some of his non-alien roles too. His performance in Cobra is basically a masterclass in 80s villainy, and it’s wild to see how much range he has when he’s actually allowed to talk.
