Stellan Skarsgård, who worked alongside Robin Williams in the 1997 film Good Will Hunting, shared insights into Williams’ distinctive nature during a Q&A event held in Los Angeles. The conversation revolved around Williams’ unique approach to humor and performance, highlighting the survival aspect of his comedy.
Skarsgård described Williams as calm and gentle when they were alone, but noted a dramatic shift when others joined the group.
“As a person, when you were alone with him, he was calm and he was nice, and he was lovely, and he could talk about anything,”
Skarsgård recalled. However, the actor added,
“But then when a couple more people came to him, he suddenly would get up — to save himself, in a way,”
and explained,
“And I think it’s a thing he had from school. He had to be funny to survive.”
This observation underscores the driving force behind Robin Williams survival humor and its impact on his interactions.
Williams’ Relentless Drive for Perfection in Filming
Gus Van Sant, director of Good Will Hunting, also shared memories of Williams’ commitment to capturing every nuance in his performance. Van Sant recalled how Williams insisted on multiple takes, striving for variations that explored different moods and styles.
“Robin was the one that was like, ‘One more, one more, one more,’”
Van Sant said.
“So we did 10 [takes] sometimes as opposed to maybe three, because he wanted to do a fast one, a slow one, a happy one, a sad one, a funny one, a not-funny one.”
Skarsgård admired this exhaustive process, explaining how it reflected both Williams’ dedication and his urgent need to express every creative impulse.
“It was fantastic because, as you said, he wanted to do new takes,”
Skarsgård said.
“And he also had a thing that was kind of a necessity for him because… he’d get an idea about a joke, for instance, and he had to produce it and get it out of the body. He couldn’t live with it inside. And I felt all the time that he had three parallel brains working, and very fast!”
The Impact of Williams’ Performance Style on Co-Stars
The intensity of Williams’ performance challenged Skarsgård and their fellow actors, pushing everyone to adapt to the shifting tones of each scene.
“The good thing was that he did different takes and they were really different,”
Skarsgård noted.
“Some were very dark, and some were very funny. And all the other actors, we were hanging in there. We were playing different kinds of scenes with him.”
This versatility enriched the film’s emotional depth and tested the cast’s flexibility.
Skarsgård also praised the skill of the director and editors in balancing Williams’ multifaceted footage. He said to Van Sant,

“The material you got [from Robin] is very interesting, because you could have cut that role into becoming a very farcical role, or you could have cut it into becoming really depressive. And you found your way.”
The careful editing ensured that Williams’ complex performance contributed to the film’s resonance and coherence.
Portraying the Intellectual Challenges Within the Film
In Good Will Hunting, Skarsgård played Gerald Lambeau, an MIT math professor who guides the young prodigy Will Hunting, portrayed by Matt Damon. To support the film’s accurate portrayal of advanced mathematics, real-life mathematician John Mighton was brought in to coach the actors, and he even appeared in the film as Gerald’s assistant, Tom.
Skarsgård acknowledged his own limitations with the technical aspects of his role, admitting,
“I did not understand it. It was far above my math knowledge.”
He valued Mighton’s presence and expertise during filming.
“We had a very good math professor that taught us and that helped us,”
Skarsgård said. Van Sant reinforced this, noting,
“You wanted to have him around all the time, so he was usually busy.”
Skarsgård added,
“If you were explaining something, the only thing you have to know is that it’s expressed the right way… You don’t have to really understand it.”
The Lasting Importance of Robin Williams’ Humor and Work Ethic
The reflections shared by Stellan Skarsgård and Gus Van Sant reveal how Robin Williams survival humor was both a coping mechanism and an artistic tool that shaped his professional and personal life. His relentless effort to capture every facet of a scene, combined with an urgent need to express jokes and ideas, deepened his work and influenced everyone around him.
This layered approach to performance not only helped create an Oscar-winning film but also shed light on the complexities behind Williams’ public persona. As audiences continue to appreciate Williams’ legacy, understanding the motivations behind his humor adds richness to his enduring impact on film and comedy.
