Warning: Spoilers for Glass Onion: A Knives Out Mystery ahead.
After a brief stint in theaters back in November, Glass Onion: A Knives Out Mystery is streaming now on Netflix (read our full review here). And this onion isn’t making many people cry. As of Wednesday, Glass Onion is the top movie on the streaming service, and it’s earned a “universal acclaim” rating on Metacritic and a certified fresh rating of 94% on Rotten Tomatoes.
Here are answers to some of the questions people are asking about the film, its twist-filled ending and the celebrity cameos and other Easter eggs dropped along the way.
Glass Onion ending explained
Here come the spoilers.
In a very Agatha Christie setup, a group of friends gather on an isolated Greek island for a weekend getaway. They’re staying at a mansion with a domed glass top dubbed the Glass Onion.
Elon Musk-esque billionaire Miles Bron (Edward Norton) has called the group of old friends together, supposedly to solve his own murder, but somehow detective Benoit Blanc (Daniel Craig) has finagled an invite. Blanc foils the fake murder Miles had set up for himself, and then the real murders appear to begin. Gun-toting Duke (Dave Bautista) drinks from Miles’ glass and dies shortly thereafter. And Miles’ former business partner Andi (Janelle Monae) appears to have been shot. (Except the bullet lodged in a journal she was carrying in a front and she’s fine.)
But this is a twisty film, and viewers soon learn Andi died before the island getaway, supposedly by suicide. Her twin sister, Helen, however, is convinced the death involved foul play. So she keeps her sister’s death under wraps and goes on the trip pretending to be her twin to try to dig deeper and solve the murder. She hires Blanc to pretend he was given an invitation and come along.
Turns out everyone had a motive to kill Andi. She and Miles started a tech company, Alpha, based on a business strategy Andi sketched on a napkin at their favorite bar, the Glass Onion. Miles copied the napkin sketch and pretended it was his idea, and the others all lied in court to support his claim because he was helping them financially. But some time later, Andi found her original napkin sketch, which unlike the copy, has the Glass Onion’s logo on its napkin, proving hers was the original. She stupidly alerted all the friends to her find, so technically, all of them had a reason to want her dead (since all of them lied in court, a fact that could seriously damage their reputations if it gets out).
The killer ends up being Miles, of course, who offed his ex-partner and tried to make it look like a suicide. Duke later told Miles he knew about the murder, and that explains why Miles killed him — by putting pineapple juice, something Duke’s allergic to, in his drink. (Apparently reactions to pineapple allergies can indeed be deadly.)
Miles manages to burn the all important napkin, prompting an outraged “Andi” (who’s really Helen) to break all his glass statues, with the other guests who secretly hate and resent Miles eventually joining in the destruction-fest. Alpha’s big new product is a hydrogen fuel called Klear, and Miles is pushing it despite knowing it’s dangerous. Andi left the company over this. Blanc gives the revenge-minded Helen a chunk of Klear, and she blows up the Glass Onion with it.
Which wouldn’t be as big of a deal except Miles has somehow rented the Mona Lisa from Paris’ Louvre, claiming the museum was closed due to COVID-19, and “France needed money” (yes, that’s how rich he is). The museum insisted the painting be behind fireproof glass, but Miles installed an override. Helen hits the override and we all get to watch the world’s most famous artwork melt. The last scene shows police boats streaming toward the island as all the other guests vow to turn on Miles, now exposed as a double-murderer and the man who destroyed the Mona Lisa.
Glass Onion celebrity cameos
The cast is pretty star-studded, with Kate Hudson, Leslie Odom Jr., Kathryn Hahn, Norton and Craig among the cast. But there are some fun cameos to watch for.
‘Among Us’ celebrity call
Early on, Blanc is seen in the bath playing the game Among Us with four buddies via an online call. Those buddies aren’t just regular people, they’re actress Angela Lansbury, basketball legend Kareem Abdul-Jabbar, composer Stephen Sondheim and actress Natasha Lyonne. (Sadly, Lansbury and Sondheim have died since the movie was filmed.)
Hey, if Miles can afford to rent the Mona Lisa in this world, he can also afford to keep tennis icon Serena Williams on call as his virtual personal trainer. She shows up on a big video screen and tries to get Blanc to work out.
Hugh Grant doesn’t have a big role, but he’s seen briefly as someone who answers the door at Blanc’s place (partner? friend?). Like many others, he apparently spent the pandemic in the kitchen baking.
Cellist Yo-Yo Ma appears early on as a guest at a wild, chichi party. His musical knowledge helps Kate Hudson’s character, Birdie, figure out how to solve the puzzle box that contains her island invitation from Bron.
Actor Joseph Gordon-Levitt is heard, but not seen. Miles has a clock of some kind that announces a musical “bong!” every hour, and Gordon-Levitt voices the word.
Actor Ethan Hawke has a brief and odd scene as one of Bron’s employees. He squirts a magical COVID-19 preventative (or something?) into each guest’s mouth before they board a boat to go to the island, allowing them to take off their masks, and freeing up the plot from having to touch on pandemic precautions. Still, there are plenty of references to the “pando,” and how it’s kept everyone indoors for far too long.
Where was the film shot?
Bron takes his friends to his supposed “private island” in Greece. Production designer Rick Heinrichs told Conde Nast Traveler those scenes were shot at a luxury resort called Amanzoe, located near Porto Heli, with other scenes filmed on the Greek island of Spetses. (Maggie Gyllenhaal’s 2021 movie The Lost Daughter was also shot on Spetses.)
The film’s opening party scene was shot in Belgrade, Serbia, the film’s costume designer, Jenny Eagan, told Men’s Health. And Heinrichs confirmed Serbia got a lot of Glass Onion love, saying, “Anything set in New York or the Northeast was created in Serbia.”
Can rich people really rent the Mona Lisa?
In the film, Miles Bron pays big bucks to Paris’ Louvre Museum to borrow the famed Mona Lisa painting. The 500-year-old masterpiece has indeed left the Louvre at various times, though not at the whim of a rich guy who wanted to hang it in his Greek pleasure palace.
During World War II, the French moved it around to a variety of places to protect it from the Nazis. Before that, in 1911, it was stolen, only to be found when one of the thieves attempted to sell it.
The Mona Lisa also was exhibited in Washington DC and New York in 1962 at the request of then-First Lady Jacqueline Kennedy. It last left the museum
In 2019, the director of the Louvre, Jean-Luc Martinez, said the museum would not include the painting in a traveling exhibition of France’s masterpieces because it is just too fragile.
But the painting does have a very protective setup, just like it does in Glass Onion. Since 2005, it’s been hanging inside a temperature-controlled box, behind bullet-proof glass.
Glass Onion ice cream actually exists
No, really. Van Leeuwen Ice Cream made a Glass Onion ice cream flavor. (You can buy it online to be shipped to you with dry ice.) The flavor honors the film by blending vanilla ice cream with Greek yogurt for the Greek setting, honeycomb candy for a glassy crunch, and a swirl of bourbon caramelized onion jam. I’ve sampled it, and while the onion smell is immediately upsetting, the cooked-in onions are so sweet that it’s … almost OK?
The Beatles connection to Glass Onion
In the film, “glass onion” refers to the giant glass dome on Miles Bron’s Greek mansion. Beatles fans, of course, know the title as a 1968 song from the band’s famous White Album. Johnson knew he wanted a title relating to glass, and told Deadline that when he searched the word “glass” in his phone’s music app, the Beatles’ Glass Onion showed up, and he was inspired. The song plays over the closing credits.
“But I was always surprised, when I was showing the script around, how many people didn’t know it was a Beatles song,” Johnson said. “I thought everybody knew Glass Onion, but I guess they don’t.”
There’s another Beatles reference. In Bron’s first scene, he’s attempting to play the band’s song Blackbird on the guitar, and claims the instrument he’s using is the one on which Paul McCartney wrote that song. He then hugs Birdie and tosses the guitar carelessly to the beach while she looks horrified.
Will there be a Glass Onion sequel?
Glass Onion itself is a sequel of sorts. Daniel Craig’s detective character, Benoit Blanc, first appeared in 2019’s Knives Out, though the rest of the cast is new. Netflix bought two sequels to Knives Out, so expect another Blanc detective film, probably with an entirely new cast, to show up eventually. Director Rian Johnson told Deadline he knows he’ll need to keep the franchise fresh and not just rehash the first two films. There’s no release date or title yet.
