Before the cameras ever rolled on Willow in 1987, one of the film’s most important pieces was still missing.

Director Ron Howard had his world, his story, and his central characters. But Madmartigan — the rogue swordsman who would bring energy, unpredictability, and humor into the film — remained undefined.

The search had been extensive.

Actor after actor came in, each offering their version of the character. Most approached the role in a familiar way: composed, heroic, controlled. They played Madmartigan as a traditional leading man — someone steady, strong, and predictable.

Technically, it worked.

But something was missing.

Howard wasn’t just looking for someone who could play the role.

He was looking for someone who could make it feel alive.

Then Val Kilmer walked into the audition.

What followed wasn’t what anyone expected.

It wasn’t polished. It wasn’t restrained. And it certainly wasn’t safe.

Kilmer didn’t treat the lines as something fixed. He bent them. Twisted them. Smirked through them. His delivery shifted mid-sentence, moving from confidence to sarcasm to something almost reckless — all in the same breath.

Where others had tried to control the character, Kilmer let it slip just out of control.

And suddenly, Madmartigan wasn’t theoretical anymore.

He was there.

Howard later described moments like these not as discoveries, but as recognitions — the feeling of seeing something that already exists, fully formed, waiting to be noticed.

That’s what Kilmer brought into the room.

Not an interpretation.

A presence.

By the time production began later that year, deep in the rugged landscapes of Wales, that same energy followed him onto the set.

Filming Willow was physically demanding. Long days, unpredictable weather, and action-heavy sequences tested every member of the cast and crew. Sword fights required precision. Stunts required endurance.

 

 

 

 

 

 

Kilmer embraced all of it.

He trained extensively for combat scenes, often performing his own stunts. But what stood out wasn’t just his commitment to the physical aspects of the role.

It was the unpredictability he brought into every moment.

Warwick Davis, who played the film’s title character and was still a teenager at the time, noticed it immediately. In scenes that could have easily felt mechanical, Kilmer introduced variation — small, unexpected changes that shifted the rhythm.

In the fast-moving sled chase sequence, for example, Kilmer didn’t just hit his marks.

He pushed beyond them.

A glance held a second longer. A reaction came a beat earlier. A movement extended just enough to feel spontaneous rather than rehearsed.

These weren’t accidents.

They were choices.

And they had an effect.

Scenes felt less staged.

More immediate.

 

 

 

 

 

Even in lighter moments — like the chaotic tavern escape — Kilmer resisted predictability. A slight change in posture. An exaggerated look. A subtle shift in tone. Each variation added texture to the performance.

Editors later found themselves with multiple usable versions of the same scene — each slightly different, each equally compelling.

It gave the film flexibility.

But more importantly, it gave it life.

Off camera, that energy didn’t disappear.

Kilmer stayed engaged between takes, maintaining a level of presence that kept scenes moving forward. Not in a rigid or overly methodical way, but with enough consistency to sustain momentum.

His co-stars felt it.

There was a sense that anything could happen — that a scene might evolve in real time rather than follow a fixed path.

And that unpredictability became contagious.

Performances sharpened. Timing improved. Interactions felt more connected.

Then there was Sorsha.

Portrayed by Joanne Whalley, the character began as an antagonist — disciplined, focused, and aligned against the film’s heroes. But as the story unfolded, her dynamic with Madmartigan introduced something more complex.

 

 

 

 

 

During filming, the connection between Kilmer and Whalley began to extend beyond the script.

It showed up in their scenes.

Particularly in the sword fight sequence — a moment designed as confrontation, but layered with something less defined. Each movement carried tension, but also a subtle undercurrent that wasn’t written into the dialogue.

It wasn’t planned.

But it worked.

Rather than pulling back, the film leaned into it.

That unspoken connection added depth, turning what could have been a straightforward rivalry into something more nuanced.

When Willow was released in 1988, audiences responded to many things — its world-building, its sense of adventure, its characters.

But Madmartigan stood out.

He wasn’t a traditional hero.

He was impulsive. Flawed. Occasionally self-serving. Often unpredictable.

 

 

 

 

 

 

And yet, that’s exactly why he resonated.

Because he felt human.

Kilmer didn’t smooth out the edges of the character.

He left them intact.

In doing so, he created something that resisted easy definition — a performance that could shift from humor to tension to sincerity without losing coherence.

It gave the film movement.

Energy.

A sense that it wasn’t simply unfolding, but evolving.

Looking back, it’s clear that casting Madmartigan wasn’t just about filling a role.

It was about finding the right kind of unpredictability — the kind that doesn’t disrupt a story, but elevates it.

Val Kilmer didn’t approach the character as something to be controlled.

He approached it as something to be explored.

And by allowing just enough looseness — just enough risk — he gave the film something rare.

A character who didn’t just exist within the story…

But helped drive it forward.
