Before he was teaching kids how to rock or voicing a kung fu-fighting panda, Jack Black was just a guy getting his arm blown off by Bruce Willis. It’s one of those "wait, was that actually him?" moments that pop up when you’re watching 90s cable at 2 a.m. In the 1997 thriller The Jackal, Black plays Ian Lamont, a sweaty, somewhat sleazy tech nerd who makes the fatal mistake of trying to upcharge a world-class assassin.
Most people know Jack Black for his high-energy comedy and infectious charm. But in the late 90s, he was Hollywood’s go-to guy for "nerd who knows too much." Honestly, seeing him in a grit-and-grime action flick feels like a fever dream now. You’ve got Bruce Willis in a series of increasingly questionable wigs, Richard Gere rocking a thick Irish accent, and then there’s Jack, just trying to survive a weapons test in the woods.
Who exactly was Ian Lamont?
In the movie, the Jackal (Willis) is hired to kill a high-ranking U.S. official. To do the job, he needs a custom-built, remote-controlled heavy machine gun mount. He finds Ian Lamont, a guy who clearly spends too much time in a basement and not enough time worrying about his personal safety. Lamont is talented, sure, but he’s also greedy.
He builds this high-tech rig for the Jackal’s Polish ZSU-23-4—a massive anti-aircraft gun. The problem starts when Lamont realizes who he’s dealing with. Instead of just taking the money and running, he tries to squeeze the Jackal for more cash, citing "technical complications." It is, quite possibly, the dumbest business move in cinematic history. You don't ask a guy who kills people for a living for an extra ten grand.

The scene that traumatized a generation
The most famous part of Jack Black’s role in The Jackal is his exit. It’s sudden. It’s messy. And it’s surprisingly dark for a guy we now associate with family-friendly movies.
The Jackal takes Lamont out to a remote field to test the gun’s accuracy. He tells Lamont to run into the field and hold up a pack of cigarettes. Lamont, being a "complete ignoramus" (as some fans put it) about the sheer power of the weapon he just helped build, actually does it. He thinks they’re just calibration testing.
- The Jackal uses a remote interface to aim.
- He locks onto the target.
- He fires a single round.
That one round doesn't just hit the cigarettes. It takes Lamont's entire arm off at the shoulder. The look on Jack Black’s face—a mix of shock, confusion, and pure agony—is actually some of his best dramatic work. Before Lamont can even process that he's become a literal "one-armed bandit," the Jackal flips the gun to full-auto and shreds him and his car. It’s a brutal, cold-blooded moment that established the Jackal as a true monster.

Why this role was a turning point
If you look at Jack Black’s filmography around this time, he was everywhere. He was in Mars Attacks!, The Cable Guy, and Enemy of the State. He was the ultimate "that guy" actor. But The Jackal was different because it showed he could handle a scene that wasn't played for laughs—even if the absurdity of the situation makes some modern viewers chuckle.
Director Michael Caton-Jones supposedly wanted someone who felt "expendable but memorable." Mission accomplished. Black brought a specific kind of frantic energy to the role that made you feel for him, even though he was a bit of a jerk. It’s the kind of performance that makes a movie stick in your brain years after the plot has faded.
Technical details and trivia
For the gearheads out there, the gun used in the scene was meant to be a 14.5mm KPV heavy machine gun, though the movie often refers to it in more generic "high-tech" terms. The sheer "sprawl" (as Lamont calls it) or spall of the impact was meant to demonstrate why this weapon was a game-changer for the plot.

Interestingly, Jack Black has talked about this role in interviews, often joking about the prosthetic arm. It was a complex practical effect for the time. They had to rig a fake limb that would explode on cue while Black reacted to a "squib" or a small explosive charge. It’s a far cry from the CGI-heavy world of Jumanji or Borderlands.
Looking back at the 1997 thriller
The Jackal is often compared to the 1973 classic The Day of the Jackal, but they’re basically different species. The 90s version is a loud, explosive chase movie. While critics weren't exactly kind to it—it holds a pretty mediocre score on Rotten Tomatoes—it’s become a cult favorite for its cast and its weirdly specific moments.
Seeing Jack Black in this context is a reminder of how hard he worked to get where he is. He wasn't always the lead. He was the guy getting shot at in the woods so that Bruce Willis could look intimidating.
How to watch it today
If you want to revisit this piece of 90s history, you can usually find The Jackal on various streaming platforms like Amazon Prime or Paramount+, depending on your region. It’s worth a watch just to see the contrast between "Young Jack" and the global icon he is now.
