You know that image. The one of a woman in a skin-tight black latex catsuit, crouching on the edge of a rain-slicked gothic cathedral with two massive pistols and eyes that glow electric blue. If you’ve spent any time watching action movies over the last two decades, you know exactly who we’re talking about. But for those just diving into the eternal war between Lycans and Vampires, you might be asking: who plays Selene in Underworld?
The short answer is Kate Beckinsale.
But honestly, the "how" and "why" are way more interesting than just a name on a poster. Back in 2003, nobody—literally nobody—expected the girl from Much Ado About Nothing and Emma to become the face of a billion-dollar action franchise. At the time, Beckinsale was Hollywood’s go-to "English Rose." She was the period-drama darling who looked more at home in a corset than a combat harness.
The Woman Behind the Death Dealer
Kate Beckinsale didn't just play Selene; she redefined what a female action lead could look like in a post-Matrix world. Before Underworld, she was mostly known for her roles in Pearl Harbor and Serendipity. She was perceived as "fragile."
Director Len Wiseman (who later became her husband, though they've since divorced) saw something else. He saw a cold, calculating intensity that fit the "Death Dealer" archetype perfectly.
Why Her Casting Was Such a Gamble
- The "Jane Austen" Problem: Critics and casting directors thought she was too soft. She even admitted in interviews that she "ran like a girl" and had never fired a gun before training for the first film.
- Physicality: She had to undergo grueling training to make the stunts look believable. We’re talking about jumping off buildings and swinging from wires while looking like a 600-year-old predator.
- The Voice: Selene isn't just a fighter; she’s a weary soldier. Beckinsale brought a posh, icy gravitas to the role that separated Underworld from the cheesier B-movie horror flicks of the early 2000s.
Who Plays Selene in Underworld Across the Sequels?
Consistency is rare in Hollywood. Usually, after three movies, actors get bored or the budget dries up. But Kate Beckinsale stuck it out for almost the entire run.
She played Selene in:
- Underworld (2003)
- Underworld: Evolution (2006)
- Underworld: Awakening (2012)
- Underworld: Blood Wars (2016)
Wait, what about Underworld: Rise of the Lycans? That’s the third movie, released in 2009. If you watch that one and wonder where Selene is, you aren't crazy. It’s a prequel. It focuses on the origin of the war and stars Rhona Mitra as Sonja. Sonja is the daughter of the vampire elder Viktor, and she looks remarkably like Selene. This is intentional within the lore—Viktor basically turned Selene because she reminded him of the daughter he executed.
But as far as Selene goes? It’s Beckinsale’s show.
Did Anyone Else Ever Wear the Suit?
Technically, yes. If we’re being pedantic, there are a couple of other "Selene" appearances, though they aren't Kate Beckinsale in the flesh.
In Underworld: Evolution, we see flashbacks of Selene as a child. That little girl? That was actually Lily Mo Sheen, Kate Beckinsale’s real-life daughter with actor Michael Sheen (who, ironically, plays the Lycan leader Lucian in the same franchise). Talk about a family business.
There’s also an animated three-part series called Underworld: Endless War. In that one, Selene is voiced by Laura Harris. While it’s still the same character, the voice is a bit different, which threw some hardcore fans for a loop when it first dropped.
Why the Character Still Matters in 2026
Even now, years after the last film, people are still obsessed with Selene. Part of it is the aesthetic, sure. But mostly, it's because Selene wasn't a "female version" of a male hero. She was a master strategist who happened to be a vampire.
She didn't lead with her sexuality, even though the marketing definitely leaned into it. She led with a "passion for truth, albeit laced with vengeance," as the official character bios put it. She was an anti-hero before they were everywhere on Netflix.
Actionable Insights for Fans
If you're looking to binge the series or just want to appreciate the performance more, keep an eye out for these details:
- Watch the eyes: The transition between her "human" blue eyes and the "vampire" glowing blue was one of the first major uses of that specific digital effect in horror-action.
- The Combat Style: Notice how Selene’s fighting style changes. In the first movie, she relies heavily on firearms. By Blood Wars, she’s basically a mystical powerhouse with Nordic-enhanced abilities.
- The Family Connection: Knowing that Lucian (the villain) is played by her ex-partner and the child Selene is played by her actual daughter makes the emotional stakes of the first two films feel way more grounded.
When you ask who plays Selene in Underworld, you’re really asking about the career-defining pivot of Kate Beckinsale. She took a character that could have been a 2D comic book trope (Selene was actually inspired by the X-Men villain Selene Gallio) and made her a tragic, enduring icon of the genre.
Whether we ever see a sixth movie is anyone’s guess. Beckinsale has been hot and cold about returning. But for now, her four-film (and one cameo) run stands as a masterclass in how to transition from "period drama star" to "action legend."
To get the full experience, start with the 2003 original. Skip the third one if you're only there for Kate, then head straight into the chaos of the later sequels where the world-building gets truly wild.
Next Steps for Your Rewatch:
- Start with the 2003 original to see the "Jane Austen" version of Kate Beckinsale vanish in real-time.
- Compare the choreography between the first film and Awakening to see how the stunts evolved with technology.
- Check out the "Endless War" anime if you want to see how Laura Harris handled the voice compared to Beckinsale’s iconic delivery.
