When you think of the 1964 Disney classic Mary Poppins, your brain probably goes straight to Julie Andrews spinning on a hilltop or Dick Van Dyke’s... let's call it "unique" Cockney accent. But the heart of the movie really rests on the shoulders of two kids. Specifically, the mischievous, kite-flying Michael Banks. If you've ever wondered who played Michael Banks in Mary Poppins, the answer is Matthew Garber.
He was just seven years old when he stepped onto the set of what would become one of the most beloved films in cinematic history. Matthew wasn't some seasoned child actor with a pushy stage mom. He was a kid with a messy mop of hair and a natural, slightly skeptical squint that made him the perfect foil to the magical nanny. He felt real. Unlike some of the overly polished child stars of the era, Garber had this genuine, slightly confused energy that made you believe he actually was a boy whose father cared more about bank ledgers than tea parties on the ceiling.
The Boy Behind the Boisterous Michael Banks
Matthew Garber wasn't originally looking for stardom. He was born in London in 1956 to parents who were both performers, so the industry was in his blood, but he wasn't exactly hunting for the spotlight. It was actually Karen Dotrice—the girl who played Jane Banks—whose father, Roy Dotrice, suggested Matthew for the role. Roy was an actor himself and knew the Garbers. He told Disney’s casting directors that there was this little boy with "artful dodger" qualities who might fit the bill.
They looked at him. They loved him.
The chemistry between Garber and Dotrice wasn't faked for the cameras; they were legitimate friends. When you see them whispering to each other or looking genuinely terrified of the "Bird Woman," that's real childhood rapport. Disney actually cast them together in three different films: The Three Lives of Thomasina, Mary Poppins, and The Gnome-Mobile. By the time they were filming The Gnome-Mobile in 1967, they were essentially a package deal. Karen Dotrice has spoken often in interviews about how Matthew was like a brother to her. She described him as a bit of a daredevil, someone who loved being a "boy" in the most traditional, muddy-knees sense of the word.
Why Matthew Garber Disappeared from Hollywood
After 1967, Matthew just... stopped. Most people assume he grew up, got bored, or suffered from the "child star curse" of being unable to find adult work. That wasn't it. He actually chose to walk away. He went back to school, lived a normal life in London, and by all accounts, was a pretty regular teenager. He wasn't chasing the ghost of Michael Banks.

Then things took a devastating turn.
In the late 1970s, Matthew traveled to India. This wasn't for a film role or a press tour. He was just a young man in his early 20s exploring the world. While there, he contracted hepatitis. By the time his father could get him back to London for medical treatment, the disease had already begun to ravage his body. It eventually spread to his pancreas.
Matthew Garber died on June 13, 1977. He was only 21 years old.
It’s a gut punch for fans of the movie. We see him eternally frozen at age seven, demanding his tuppence back from the bank, and the reality that he didn't even make it to his 25th birthday is hard to square with the joy he brought to the screen. For years, rumors swirled about how he died—some darker than others—but his brother, Fergus Garber, eventually set the record straight in interviews. It wasn't drugs or some wild lifestyle. It was a tragic, accidental infection from tainted meat that turned into a medical nightmare.
The Legacy of the "Tupperne" Boy
When we look back at who played Michael Banks in Mary Poppins, we shouldn't just see a tragic footnote. We should look at what he actually achieved in those few years on screen.

Garber was named a "Disney Legend" posthumously in 2004. It’s an honor usually reserved for people who spent forty years drawing Mickey Mouse or building theme parks. Giving it to a kid who only made three movies says a lot about the impact of his performance. He didn't just read lines. He held his own against Julie Andrews, who was at the height of her powers, and David Tomlinson, a master of comedic timing.
Think about the scene in the bank. Michael Banks is terrified, yet defiant. He’s standing up to the most powerful men in London because he wants to feed some birds. Garber’s performance in that moment is the pivot point for the entire movie’s theme. It’s not about magic umbrellas; it’s about a son trying to reach a father who has forgotten how to be a person.
Modern Comparisons and the 2018 Sequel
When Disney decided to make Mary Poppins Returns in 2018, they had the impossible task of casting a "new" Michael Banks. This time, the character was an adult, played by Ben Whishaw.
Whishaw is a brilliant actor, and he brought a fragile, grieving soul to the role. But if you watch closely, you can see he’s channeling some of Garber’s original DNA. The way he tilts his head, the specific cadence of his frustration—it’s all a nod to the boy who first wore the flat cap and the overcoat in 1964.
Karen Dotrice actually made a cameo in the 2018 film as an elegant woman on the street asking for directions. It was a bittersweet moment for long-time fans. Seeing "Jane" as a grandmotherly figure reminded everyone of the empty space where "Michael" should have been.

What You Should Take Away From Matthew Garber’s Story
It is easy to get lost in the trivia of Hollywood, but Matthew Garber's life is a reminder that the people behind our favorite childhood memories were real humans with real, often short, lives. Honestly, it’s kinda remarkable that someone who spent so little time in front of a camera left such a permanent mark on culture.
Most child actors from the 60s are either totally forgotten or ended up on reality TV. Garber stayed "Michael" forever.
If you want to honor his memory, don't just remember how he died. Remember the way he looked at the carousel horse when it broke off the track. Remember the way he tried to hide a smile when Mary Poppins gave him his "medicine."
Actionable Insights for Fans and Historians
If you're looking to dive deeper into the history of the Banks family actors, here are a few things you can actually do:
- Watch The Three Lives of Thomasina: This is often overlooked but features Garber and Dotrice in their first pairing. It’s a weirder, darker film than Poppins, but their chemistry is even more evident.
- Check the Disney Legends Archives: The official Disney fan club (D23) has digital archives with the full citation for Garber's induction. It’s a great read for those who want to see how the studio viewed his contribution decades later.
- Visit the Locations: While Mary Poppins was filmed almost entirely on a soundstage in Burbank, California (Stage 4, now named the Julie Andrews Stage), you can still visit the real London streets that inspired the Cherry Tree Lane aesthetic, such as the areas around Kensington Square.
- Listen to the Original Soundtrack: Pay close attention to the track "I Step in Time." You can hear Garber's actual voice—not a studio singer—shouting along with the chimney sweeps. It captures his energy better than any biography ever could.
Matthew Garber wasn't just a child actor who got lucky. He was a kid who perfectly captured the spirit of childhood rebellion and wonder, and that is why we are still talking about him over sixty years later.
