You know that feeling when you're watching a black-and-white classic and the kid on screen is just... too good? Most child actors in the 1940s were coached within an inch of their lives. They had the Shirley Temple curls and the rehearsed "gee whiz" lines. But then there’s Susan Walker in the 1947 masterpiece. Natalie Wood in Miracle on 34th Street didn't feel like a child star. She felt like a real, slightly grumpy, overly logical eight-year-old.
Honestly, it's probably because she wasn't really acting. At least, not in the way we think.
The Secret Life of a Skeptic
Natalie was eight when she stepped onto the set at Macy’s Herald Square. Her character, Susan, was basically a miniature adult. Her mother, Doris (played by the legendary Maureen O'Hara), had raised her to be a "realist." No fairy tales. No giants. And definitely no Santa Claus.
But here’s the kicker: while Susan Walker was busy being a skeptic, the real-life Natalie Wood was completely convinced.
She truly believed Edmund Gwenn, the actor playing Kris Kringle, was the real deal. It wasn't just a hunch. She saw him on set every day. He was kind. He had that twinkle. He even grew his own beard for the role—which Natalie famously tugged on during filming to check if it was fake. It didn't budge.
Gwenn was so committed to the bit that he never let Natalie see him without the suit or the beard during the entire shoot. He’d arrive hours early for the transformation. To an eight-year-old girl, the logic was simple: if he looks like Santa, acts like Santa, and has a beard that doesn’t fall off when you pull it, he’s probably Santa.
When the Magic Broke
Every classic story has a "moment," right? For Natalie, that moment happened at the wrap party.
Imagine being eight. You’ve spent months hanging out with Santa Claus. You’ve filmed a movie where you finally learn to believe in him. Then, you walk into a party and see a short, balding man with no beard and glasses.
That was Edmund Gwenn.
Natalie later admitted she "just couldn't get it together" after seeing him clean-shaven. It was iconoclastic. Her world shattered a little bit that night. But in a weird way, that genuine, wide-eyed belief is exactly what makes her performance in Natalie Wood Miracle on 34th Street so hauntingly perfect. You can’t fake that kind of wonder.
It Was Miserably Cold
If you look closely at the scenes where they’re outside during the Macy’s Thanksgiving Day Parade, everyone looks a little... stiff. That’s because it was freezing.
Like, "cameras literally seizing up" freezing.
They filmed the 1946 parade live. There were no retakes. Edmund Gwenn actually rode on the float as the parade Santa. While he was waving to thousands of real New Yorkers, Natalie Wood and John Payne were watching from a window nearby. It was a chaotic, one-shot-only kind of day.
There’s a local legend that a woman named Vaughn Mele, who lived across the street from where they were shooting the final house scene, saw the crew shivering. She actually let them into her house to warm up. Maureen O’Hara was so grateful she eventually took the woman and her husband out for a fancy dinner.
Talk about a real-life holiday miracle.
Working Double Shifts
Natalie wasn't just working on one movie at the time. She was actually pulling double duty. In the mornings, she’d be on the set of The Ghost and Mrs. Muir playing Gene Tierney’s daughter. Then, she’d rush over to the 20th Century Fox lot to play Maureen O’Hara’s daughter for the afternoon.
She was a straight-A student, too. California law required three hours of school a day on set. Natalie was famously smart—one of the few child actors who actually liked arithmetic. Director Joseph Mankiewicz once called her the smartest "moppet" he’d ever met.
But you can see that intelligence in her eyes. Susan Walker isn't a "cute" kid. She’s a thinking kid.
Why the Movie Almost Failed
The studio, 20th Century Fox, was terrified of this movie. Head of the studio Darryl F. Zanuck thought a "Christmas movie" would only make money in December.
His brilliant plan? Release it in June.
They marketed it as a romantic comedy. The posters didn't show Santa; they showed the leads. They basically hid the fact that it was a holiday film so people would see it in the summer heat.
It worked, obviously. But it’s wild to think that Natalie Wood Miracle on 34th Street could have been a forgotten summer flop if audiences hadn't connected so deeply with that little girl and her bearded friend.
What We Can Learn From Susan Walker
The film isn't really about a trial or a department store rivalry. It’s about the "intangibles."
As we get older, we become like Doris. We want facts. We want proof. We want to see the receipts. But Natalie Wood’s character reminds us that "faith is believing in things when common sense tells you not to."
If you're looking to recapture some of that 1947 magic, here are a few ways to dive deeper into the history:
- Visit the real house: The "dream house" Susan wants at the end is a real home in Port Washington, New York. It’s still there on 24 Derby Road.
- Watch for the cameos: Keep an eye out for a young Thelma Ritter. It was her first film. She plays the mom who gets sent to Gimbels by Kris.
- Check the toothpicks: In the scene where Mrs. Shellhammer is on the phone, look at the toothpicks on the table. They signify how many martinis she’s had. It’s a very "grown-up" joke hidden in a family movie.
Natalie Wood went on to become a massive star in West Side Story and Rebel Without a Cause, but she always looked back at this role as something special. She wasn't just playing a girl who learned to believe. For a few months in 1946, she was the girl who actually did.
If you're planning a rewatch this year, pay attention to the scene where she pulls his beard. Knowing she thought she was touching the face of a legend makes that moment a thousand times better. It's the kind of authenticity you just don't see anymore.
To truly appreciate the legacy, check out the original black-and-white version rather than the colorized ones. The shadows and the grit of 1940s New York add a layer of realism that makes the "miracle" feel much more earned. Plus, you get to see Natalie’s incredible acting (and non-acting) in its purest form.
