Honestly, when you think about the 1991 classic Father of the Bride, your brain probably goes straight to Steve Martin. You think about George Banks having a full-blown meltdown in a supermarket over hot dog buns. You think about Martin Short’s indecipherable accent as Franck Eggelhoffer. But if you look closer, the whole thing would have fallen apart without father of the bride Keaton—specifically, Diane Keaton’s Nina Banks.
She wasn't just "the wife." Nina was the tactical commander of the Banks household. While George was busy falling into swimming pools and panicking about $250-a-head catering costs, Nina was the one actually making sure her daughter got married without the house burning down. It’s a role that often gets overshadowed by the broader comedy, but Keaton’s performance is actually what makes the movie feel like a real family story rather than just a series of sketches.
The Nina Banks Energy: More Than Just a Supporting Role
In most 90s comedies, the "mom" role was kind of thankless. You were usually there to roll your eyes at the dad’s antics or hand out snacks. But Keaton brought this specific "quicksilver" energy to Nina Banks. Steve Martin once mentioned in an interview that when you meet Diane, you think she’s doing an impression of herself because she’s so "lightning and erratic and crinkling with electrical charge."
That’s exactly what she gave Nina.
Nina Banks wasn't a pushover. Remember the scene where George is in jail after his supermarket breakdown? She doesn't just show up and hug him. She bails him out on the strict condition that he stops ruining their daughter’s life. She was the backbone. It’s a nuance that's easy to miss when you're laughing at George trying to fit into his old tuxedo.
Disney Actually Didn't Want Her
This is the part that usually shocks people. Despite being an Oscar winner for Annie Hall, Disney was super hesitant to cast Diane Keaton in Father of the Bride. Why? Because her previous film, The Good Mother, hadn't done well at the box office.
Hollywood is a "what have you done for me lately" kind of town.
Nancy Meyers and director Charles Shyer actually had to beg the studio to let her play Nina. They knew they needed someone who could match Steve Martin’s comedic timing but also keep the movie grounded in actual emotion. Without that push, we might have seen a completely different—and likely much less "souly"—version of the Banks family.
That 2020 Reunion: Father of the Bride Part 3(ish)
Fast forward nearly thirty years to the height of the pandemic. Nancy Meyers surprised everyone by dropping Father of the Bride Part 3(ish) on YouTube. It wasn't a full movie, but a "screenlife" short film shot over Zoom to benefit World Central Kitchen.
Seeing father of the bride Keaton back on screen as Nina in 2020 felt like a warm hug. The plot was basically George Banks losing his mind over hand sanitizer and social distancing (completely on brand), while Nina organized a surprise virtual wedding for their son, Matty (played by a grown-up Kieran Culkin).
It also gave us some wild casting additions:
- Florence Pugh played Megan Banks (the baby from the second movie).
- Ben Platt played "Georgie," Annie’s son.
- Robert De Niro even showed up as the father of Matty's fiancée.
Even in a Zoom box, Keaton’s Nina was the one facilitating the connection. She was the one who kicked off the call. She was the one holding the family together across miles of fiber-optic cables.
A Legacy That Quietly Changed Everything
Most people don't realize that Father of the Bride was the second of five collaborations between Nancy Meyers and Diane Keaton. They basically invented a specific aesthetic—the "Nancy Meyers Kitchen" vibe. You know the one: white cabinetry, bowls of perfectly curated citrus, and a sense of upper-middle-class comfort that feels both aspirational and lived-in.
But beyond the decor, the movie dealt with the "impossible tenderness of letting go," as some critics put it. While the title says "Father," the emotional heavy lifting often happened in the quiet glances between Nina and Annie. Nina had to balance her husband’s grief over losing his "little girl" with her own excitement for her daughter’s future. It’s a tightrope walk.
Sadly, the world lost Diane Keaton in late 2025 at the age of 79. When the news broke, the tributes from her Father of the Bride co-stars weren't just about her acting; they were about her presence. Steve Martin and Martin Short both spoke about the "light" she brought to the set. She wasn't just a co-star; she was the heartbeat of that fictional San Marino home.
How to Revisit the Banks Family Today
If you’re looking to scratch that nostalgic itch, don't just stop at the first movie. The sequel, Father of the Bride Part II, is actually one of those rare cases where the second film holds its own, mainly because it explores Nina and Annie being pregnant at the same time.

- Watch the 1991 Original: Pay attention to Nina’s wardrobe. It’s a masterclass in 90s "California Chic" that people are still trying to replicate on Pinterest today.
- Check out the 2020 Short: It’s still on Netflix’s YouTube channel. It’s only about 25 minutes long but features the entire original cast.
- Compare to the 1950 Version: If you really want to see how much Keaton changed the dynamic, watch the Spencer Tracy and Joan Bennett original. The "mother" role in 1950 was much more traditional; Keaton’s Nina feels like a partner, not just a passenger.
Whether you're watching it for the first time or the fiftieth, it's clear that the "Keaton Factor" is what kept the franchise from being just another silly comedy. She gave it gravity. She gave it grace. And she made us all wish we had a Nina Banks in our corner when life gets a little too chaotic.
Start by queuing up the 1991 film on Disney+ or your preferred streaming service and watch for those small, wordless moments between Keaton and Martin—that's where the real magic of the movie lives.
