Thirty Days of Work for a Lifetime of Questions. Emma Thompson Explains Why Harry Potter Fame Feels Like a Strange Mismatch
Unexpected legacy.
Thirty days of work. A lifetime of questions. That’s the strange mismatch Emma Thompson just described when she talked about her role in the Harry Potter films. The Oscar-winning actress, who played the eccentric Professor Sybill Trelawney across three movies, told the SmartLess podcast she spent only about 30 days total on set for the entire franchise. Yet, decades later, fans still bring it up like it was the defining chapter of her career.
According to PEOPLE, Thompson, 67, appeared on the June 29 episode of the podcast, hosted by Jason Bateman, Will Arnett, and Sean Hayes. The conversation quickly turned to her time in the wizarding world when Hayes, a self-proclaimed “massive” Harry Potter fan, mentioned her character’s thick glasses and neurotic energy. Thompson confirmed the role with a tired joke, “She said, fatigued,” before explaining how she approached the part.
Trelawney, the Divination professor who occasionally predicts doom with eerie accuracy, was already fully realized in J.K. Rowling’s books. “I think she’s definitely nearly blind, can’t see anything, and obviously deeply neurotic because she can see sometimes whether people have the grim or not,” Thompson said.
The disconnect between the time she spent filming and the cultural footprint her role left behind still baffles her
“Honestly, in my quite long career, given the fact that I’m a good 10 years older than all of you guys, I have done many, many parts and I’ve spent about 30 days on Harry Potter in my whole life,” Thompson told the hosts. “So it’s kind of a strange thing to talk about because it’s become such this huge phenomenon, and that’s a lot of the time what people are very drawn to.”
It’s a sentiment she’s expressed before, marveling at how a few weeks of work can overshadow decades of other performances. For an actress who’s played everything from Elinor Dashwood in Sense and Sensibility to the magical Nanny McPhee, it’s understandable why the fixation on Trelawney might feel disproportionate.
But Thompson isn’t dismissing the franchise’s impact. If anything, her comments reveal a deep respect for the audiences who grew up with these stories. When the conversation shifted to acting in films for young people, she called children “the sacred audience.” “They’re the people we need to make the best of our work for because it’s the first time that they see something,” she said. “It needs to be so, so good.”
That philosophy explains why she’s gravitated toward so many family-friendly projects over the years. Beyond Harry Potter, she lent her voice to Pixar’s Brave, played Mrs. Potts in Disney’s live-action Beauty and the Beast, and starred in Matilda the Musical. Nanny McPhee, a film that she both wrote and starred in, became a touchstone for a generation of kids.
The Harry Potter films themselves were a cultural juggernaut
The franchise spanned eight movies released between 2001 and 2011 and grossed over $7 billion worldwide. A new TV adaptation is already in the works, set to premiere on HBO in Christmas 2026.
For Thompson, though, the franchise’s legacy is a reminder of how fleeting on-screen moments can be. She’s the only person to win Oscars for both acting (Best Actress for Howards End in 1992) and screenwriting (Best Adapted Screenplay for Sense and Sensibility in 1995), yet even she can’t escape the gravitational pull of Hogwarts.
Her perspective on the industry’s treatment of women over 60 adds another layer to her thoughts on legacy. Last month, Thompson called out filmmakers for sidelining older actresses after a damning study revealed just how rare it is to see women her age in leading roles.
According to The Independent, the ‘Age Without Limits’ campaign found that only five of the 100 highest-grossing films from the past three years starred a woman over 60. For context, movies were four times more likely to feature a talking animal as the lead than an older woman. Thompson didn’t hold back in her response. “Women are half the population, and we get older,” she said. “So where are the stories about us? The older we get, the more interesting we are.”
Thompson’s approach to acting has always been about commitment
When Arnett pointed out how actors joining a franchise midway have to “make a choice” about their performance’s tone, she agreed. “You just have to fling yourself into it, don’t you? At first, and hope that your instincts are right,” she said.
That philosophy explains why Trelawney feels so vivid, even in her limited screen time. Thompson’s instincts were spot-on – she made the character unmistakably hers, from the coke-bottle glasses to the nervous energy that made every prediction feel like a genuine psychic event.
For fans, Trelawney is unforgettable. For Thompson, she’s just one of many roles in a career that’s spanned over 40 years. She clearly understands why Harry Potter resonates so deeply with people. But it’s a reminder that an actor’s legacy isn’t always tied to the time they spend on a project. Sometimes, it’s about the impact a single character can have on millions of viewers, especially the youngest ones.
Thompson’s latest project, The Sheep Detectives, is now streaming on Amazon Prime.
