Honestly, if you grew up in the late eighties or early nineties, you probably remember the absolute chokehold the "Brat Pack" had on the box office. But when it came to Westerns, people didn't expect much until Young Guns hit. Then came the 1990 sequel. While everyone was busy talking about Emilio Estevez's manic laugh or Jon Bon Jovi's "Blaze of Glory," there was one guy who basically stole every scene he walked into.
Christian Slater.
Specifically, Christian Slater in Young Guns II as "Arkansas" Dave Rudabaugh.
Most people forget that Slater wasn't even in the first movie. He was the "new guy" brought in to replace the void left by Charlie Sheen's character, Dick Brewer, who—spoiler alert for a thirty-year-old movie—didn't make it out of the first film alive. Slater brought this chaotic, twitchy energy that the sequel desperately needed. He wasn't just another guy with a gun; he was the internal friction that made the gang's dynamic actually feel dangerous.
Who Was Arkansas Dave Rudabaugh Anyway?
In the movie, Slater plays Dave Rudabaugh as a fame-hungry, arrogant outlaw who’s constantly measurement-checking his ego against Billy the Kid. He’s obsessed with his own "score"—claiming he's killed 65 men, "not counting Mexicans and Indians." It's a dark, gritty role that Slater played with a signature smirk that made him look like he was having way too much fun.
The real Dave Rudabaugh was arguably even scarier. History remembers him as "Dirty Dave," and he was the only man Billy the Kid was said to truly fear.
Unlike the loyal-ish version of the character in the film, the historical Rudabaugh was a bit of a nightmare. He was a train robber and cattle rustler who actually rode with the Dodge City Gang before ever crossing paths with Billy. Slater captures that "wild card" essence perfectly. You never quite know if he’s going to back Billy up or shoot him in the back just to take over the gang.
That tension is the engine of the movie.
The Power Struggle: Billy vs. Dave
The best parts of the film aren't the big shootouts. They’re the quiet, tense moments where Dave tries to undermine Billy's leadership.
Slater uses this specific brand of "Heathers-era swagger." He’s got that Jack Nicholson-esque drawl and the arched eyebrows. When he tells Billy, "I'm the one they should be writing stories about," you almost believe him.
He makes Dave Rudabaugh feel like a rockstar who's stuck as the opening act. It’s a brilliant bit of casting because, in 1990, Slater was the rising star who was technically "opening" for the established fame of Estevez and Kiefer Sutherland. The meta-narrative just worked.
What Most People Get Wrong About Slater's Role
A lot of casual viewers think Dave Rudabaugh was just a fictional character added for flavor.
Nope.
While the movie takes massive liberties—like the nickname "Arkansas," which the real Dave never actually used—Rudabaugh was very much a real person. He was captured alongside Billy at Stinking Springs. He even escaped from jail later, eventually meeting a pretty gruesome end in Mexico.
The movie shows him being beheaded as a warning to other outlaws. In reality, he was decapitated after a gunfight in a Mexican saloon over a card game, and his head was actually paraded through the streets on a pole.
The film's ending for him was surprisingly close to the brutal truth.
Why the Performance Still Holds Up
So, why does Christian Slater in Young Guns II still matter decades later?
It’s the levity.
The sequel is much darker than the first film. It’s about the end of an era, betrayal, and the realization that these "kids" are actually just criminals who are going to die young. Slater provides the dark humor. His delivery of lines like, "I'll make you famous!"—which actually became a bit of a catchphrase—cuts through the self-seriousness of the genre.
He also brought a physical intensity. There’s a knife fight between Slater’s character and Lou Diamond Phillips’ Chavez y Chavez that is arguably one of the best-choreographed moments in the film. It isn't clean. It's messy and desperate.
The Production Chaos You Didn't Know About
Making a Western in the 90s was a gamble.
John Fusco, the screenwriter, wanted more historical accuracy for the sequel. He got some of it, but the studio still wanted a "popcorn flick." This led to a weird hybrid of a movie.
Slater was reportedly cast because of his massive "cool factor" at the time. He had just come off Heathers and Pump Up the Volume. The producers knew that putting him in a cowboy hat would sell tickets to a younger demographic that wouldn't normally touch a Western with a ten-foot pole.
It worked.
The movie didn't just appeal to dads who liked John Wayne. It appealed to teenagers who liked rebellion.
The Legacy of the "New" Regulator
If you revisit the film today, Slater’s performance is the one that feels the most "modern."
He doesn't play it like a traditional cowboy. He plays it like a punk rocker who happens to have a Colt .45. It’s that specific energy that helped keep the Western genre alive during a decade when it was mostly considered "dead" before Unforgiven and Tombstone showed up a few years later.
Key Takeaways from Slater’s Time on the Frontier:
- He wasn't a replacement: He was a different flavor. Where Charlie Sheen was the "conscience," Slater was the "instigator."
- The History is Dark: The real Dave Rudabaugh was a terrifying figure, and Slater's "Arkansas Dave" is a stylized but effective tribute to that chaos.
- Chemistry Matters: The friction between Slater and Estevez makes the gang's eventual downfall feel inevitable. If they hadn't been fighting for the wheel, maybe they would have made it to Mexico.
If you haven't seen it in a while, it's worth a rewatch just to see Slater at the absolute peak of his "coolest guy in the room" phase. He took a secondary role and made it the centerpiece of the film's personality.
Next Steps for the Western Fan:
Go back and watch the Stinking Springs capture scene. Pay attention to Slater's face when the law finally catches up to them. It’s a masterclass in a character realizing that the "glory" he wanted is actually just a cold jail cell. After that, look up the real-life accounts of "Dirty Dave" Rudabaugh—his actual prison escape is more cinematic than anything Hollywood could have written.
