‘Glass Onion’ Lands on Netflix: Inside All the Star-Packed Cameos in Rian Johnson’s ‘Knives Out’ Sequel
Warning: This article contains spoilers for Glass Onion: A Knives Out Mystery.
After months of anticipation, Glass Onion: A Knives Out Mystery has officially dropped on Netflix — and it’s already proving to be one of the buzziest streaming events of the season.
The Rian Johnson–directed sequel to the 2019 smash-hit Knives Out brings back Daniel Craig as Southern sleuth Benoit Blanc, this time unraveling a new murder mystery in the glittering world of tech billionaires, influencers, and secrets too good to stay hidden.
Alongside its A-list cast — including Edward Norton, Janelle Monáe, Kathryn Hahn, Leslie Odom Jr., Jessica Henwick, Madelyn Cline, Kate Hudson, and Dave Bautista — the film also delivers a treasure trove of blink-and-you’ll-miss-it cameos that fans are already obsessing over on social media.
Here’s a look at the most surprising and emotional star appearances in Netflix’s Glass Onion:
Hugh Grant as Benoit Blanc’s Partner
One of the most-talked-about cameos arrives when Hugh Grant casually opens the door to Blanc’s apartment, confirming that the detective lives with a male partner.
Craig himself addressed the reveal in The Sunday Times, saying:
“You are supposed to reflect life. And that [gay] relationship reflects people in my life. It’s normal. We don’t make a song and dance out of it. It just feels right.”
Director Rian Johnson echoed the sentiment, telling the outlet that making Blanc gay “just made sense to Daniel and me,” adding:
“We didn’t want to be coy or cute about it. We just wanted it to be a fact of the character.”
The understated reveal has been hailed online as a milestone in Hollywood’s handling of LGBTQ+ characters — authentic, subtle, and refreshingly matter-of-fact.
Legends Angela Lansbury and Stephen Sondheim
In a moving farewell, both Angela Lansbury and Stephen Sondheim appear via a Zoom call with Blanc during the pandemic-era sequence, playing a round of Among Us.
Lansbury — who passed away in October 2022 at age 96 — was a beloved icon of the mystery genre through Murder, She Wrote. Sondheim, who died in 2021 at 91, was a master of puzzles and narratives that inspired countless creators.
Johnson told Entertainment Weekly:
“It means so much that they were in the movie. It means even more that I got 10 minutes with each of them to just tell them what their work meant to me.”
Also on the call? NBA legend Kareem Abdul-Jabbar and Russian Doll star Natasha Lyonne, reminding audiences that this mystery world spans far beyond Greece’s sparkling waters.
Ethan Hawke as “Efficient Man”
Ethan Hawke pops up briefly — but memorably — as a mysterious dockside man who sprays Blanc and his fellow travelers with a supposed COVID-19 antidote before their journey to Edward Norton’s character’s private island.
Johnson revealed Hawke’s cameo happened by chance while the actor was filming Moon Knight nearby in Budapest. He hopped over to Greece for a one-day shoot. His simple line — “You’re good” — has already become a fan-favorite meme.
Serena Williams, Your On-Demand Trainer
Yes, that really was tennis icon Serena Williams waiting inside the mansion’s high-tech gym mirror. At first, it looks like a pre-recorded workout video, until Williams breaks the fourth wall and casually asks Craig and Janelle Monáe’s characters if they plan to exercise.
The gag reveals that Norton’s billionaire keeps Williams on retainer as a personal trainer — the kind of over-the-top luxury flex that had Twitter laughing out loud.
Yo-Yo Ma Solves a Puzzle
Famed cellist Yo-Yo Ma makes a sophisticated cameo at Birdie Jay’s (Kate Hudson) party, helping explain the layered symbolism of one of Bron’s elaborate puzzle boxes. Fans online called it “the most cultured clue drop in movie history.”
Joseph Gordon-Levitt, the Island’s Hourly Chime
A Rian Johnson film wouldn’t be complete without Joseph Gordon-Levitt. While he doesn’t appear on screen, his voice provides the hourly “dong” chime on Norton’s island — a quirky Easter egg for longtime fans.
The Bigger Picture
Between heartfelt tributes (Lansbury and Sondheim), cultural icons (Serena Williams, Yo-Yo Ma), and delightful surprises (Hugh Grant, Ethan Hawke), Glass Onion delivers far more than just a mystery. It’s a playful love letter to art, celebrity, and storytelling itself.
And for Johnson, that’s exactly the point. “These movies are about people, and the fun of them is recognizing the world around us reflected in these wild stories,” he told EW.
With its witty script, decadent visuals, and star-powered cameos, Glass Onion: A Knives Out Mystery is streaming now on Netflix — just in time for cozy fall binge nights.
