The film features an ensemble cast including Sandra Bullock, Cate Blanchett, Anne Hathaway, Mindy Kaling, Sarah Paulson, Awkwafina, Rihanna, and Helena Bonham Carter.

They assemble their team: has-been fashion designer Rose Weil, who owes the IRS; jewelry maker Amita, who longs for more independence from her mother; security hacker Nine Ball; street hustler and pickpocket Constance; and profiteer Tammy, a housewife who fences stolen goods out of her suburban home.

Debbie plans to steal the Toussaint, a $150 million Cartier necklace, during the upcoming Met Gala, using the host, famous film star Daphne Kluger, as an unwitting accomplice.

When Rose learns the Toussaint can only be unclasped by a special magnet carried by Cartier's security detail, Nine Ball enlists her younger sister Veronica's help in creating a duplicate.

As the male Cartier guards wait outside and Daphne vomits into a toilet, Constance deftly removes the necklace from her neck and sneaks it to Amita, who splits it into smaller pieces of jewelry in the kitchen bathroom.

Having crossed paths with and sent members of the Ocean family to prison before, Frazier immediately suspects Debbie, but her careful presence on the gala's video footage gives her an unbeatable alibi.

With their payouts from the score much larger than previously promised, each member of the team goes her separate way: Amita travels to Paris with a man she meets on Tinder; Rose pays off her debts and opens her own store; Constance buys a spacious loft in the city and becomes a YouTuber; Tammy expands her business in stolen goods; Nine Ball opens a pool hall; Daphne becomes a film director (and is shown directing a lookalike); Lou takes her motorcycle on a scenic road trip; and Debbie mixes and enjoys a martini at Danny's grave, knowing he would be proud of her.

Celebrities who make cameo appearances include Anna Wintour, Katie Holmes, Maria Sharapova, Serena Williams, Richard Madden, Kim Kardashian, Common, Adriana Lima, Desiigner, Kylie Jenner, Alexander Wang, Liu Wen, Kendall Jenner, Bella Hadid, Gigi Hadid, Lily Aldridge, Olivia Munn, Jaime King, Zac Posen, Hailey Baldwin, Derek Blasberg, Sofia Richie, Heidi Klum, Kelly Rohrbach, Lauren Santo Domingo, and Rainey Qualley.

[15] In August 2016, Bullock, Blanchett, Bonham Carter, and Kaling were confirmed to star, with Anne Hathaway, Rihanna, Awkwafina, and Sarah Paulson closing deals to fill the cast.

The website's critical consensus reads, "Ocean's 8 isn't quite as smooth as its predecessors, but still has enough cast chemistry and flair to enjoyably lift the price of a ticket from filmgoers up for an undemanding caper.

[38] Writing for Rolling Stone, Peter Travers gave the film 3 out of 4 stars and praised the cast (namely Bullock, Blanchett and Hathaway), saying, "Ocean's 8 is a heist caper that looks gorgeous, keeps the twists coming and bounces along on a comic rhythm that's impossible to resist.

"[49] Alonso Duralde of TheWrap called the film "slick, charming and funny," though added "it never quite kicks into high gear" and said, "Cinematographer Eigil Bryld gives the proceedings the high-gloss of a SkyMall catalog, which is appropriate for a movie about robbing a legendary Cartier necklace at fashion's most exclusive event... And between the sheen and the talented performers, Ocean's 8 does eventually coast on froth and good will.

"[50] Variety's Owen Gleiberman said it is "clever enough to get by" and wrote "Ocean's 8 is a casually winning heist movie, no more and no less, but like countless films devoted to the exploits of cool male criminals, it lingers most... as a proudly scurrilous gallery of role models."

He found Hathaway "commanding at every moment" and believed Bullock projected "the debauched insolence" and ideological drive of "a hungry criminal", but lamented the scarcity of impressive dialogue for Paulson and Blanchett, who "don't get a chance to create indelible characters".

[52] Michael Phillips of the Chicago Tribune gave the film 2 out of 4 stars and said, "Some movies are more about parallel play than actual playground interaction, and despite a screenful of terrifically skillful talents, Ocean's 8 never quite gets its ensemble act together.

"[53] Writing for the Chicago Sun-Times, Richard Roeper said the cast "banters beautifully, but the heist is a bit too breezy", lacking a "formidable, hiss-worthy villain" and "darker, more challenging, more nuanced adventure".

[54] Manohla Dargis, writing for the New York Times, said "The bad ex angle isn't worked too hard or too long, but it means that even when women are running a multimillion-dollar con they have to make room for guy troubles, which is a drag".

Dargis classifies the film as a "needless narrative filler" and concluded that "A lot of this is fun to watch but would have been more breezily enjoyable if the movie played as lightly (and seriously) with gender as much as it does with genre.
