“The Miniature Wife” has officially crossed into Certified Fresh territory on Rotten Tomatoes, holding a 74% score across 23 critics reviews for its first season on Peacock. The headline names are Elizabeth Banks and Matthew Macfadyen. The quiet story inside the story is Sofia Rosinsky, who plays their daughter Lulu.
Lulu Littlejohn is the Littlejohns’ college-aged kid, home from school to a house where her mother is suddenly six inches tall and her father is the scientist who did it. On paper that’s a sitcom setup. On screen, Rosinsky plays it like a girl who has been keeping score in this marriage her whole life and finally has proof she was right about everything. She’s angry, she’s guarded, and she resents her mother in the specific way that only someone who is secretly very much like their mother ever resents them.
That’s the read Rosinsky herself gave when the cast talked to Metro Philadelphia ahead of the premiere. “Lulu is, I’d say, an exact split between her two parents,” she said. “She has their wit, their intelligence, but she also has all of their flaws. She’s very dramatic and she can tend to be narcissistic and self-destructive.” She called Lulu “the result of this marriage that’s been facing a lot of turbulence,” and said the part gave her room to show a young person waking up to the fact that she can choose differently than her parents did.
Critics clocked it. The Hollywood Reporter singled out a mother-daughter scene where Lulu has a small epiphany about the family’s shared awfulness, calling it one of the rare moments the show actually lets its secondary characters breathe. Collider’s review praised Rosinsky for being given real work to do, not just written as a reaction shot to the shrinking gag. Time’s review described Lulu as the moody daughter who grew up idolizing her dad and resenting her mom, and then quietly noted she “obviously has more in common with Lindy.”
If you’ve been following her, none of this is a surprise. Rosinsky, 19, has been working since she was five. She broke out as Mac Coyle in Amazon’s “Paper Girls” in 2022, played Zora Morris in Disney’s “Fast Layne,” and turned up as the mysterious Yeva in Hulu’s “Death and Other Details” in 2024. Her mother is the actress K. Louise Middleton, who trained under Sanford Meisner and coached Sofia through the technique from the start. She also runs StellaLuna Films with her older sister Alexis, and she’s a musician who studies at Berklee. She plays guitar, bass, ukulele, mandolin, drums and piano, which is a sentence that feels slightly unfair to the rest of us.
Her favorite moment to shoot, she told the Peacock Blog, comes in the finale, “A Tiny Big Idea.” Lulu is handed a bottle of her father’s untested regrowth formula and told to pour it on a shrunken Les, who is sitting in a bathtub. Rosinsky described Macfadyen crouching down and then popping up out of the tub to sell the scale.
All ten episodes of “The Miniature Wife” are streaming now on Peacock, with the Certified Fresh badge freshly attached.
