In her 2011 book, Mindy Kaling expressed an interest in wanting to do a reboot of Ocean's Eleven (2001), called Ocean's 5, that would feature an all female cast.
The eight main cast has won four Oscars, two Emmys, nine Grammys, six Golden Globes, five BAFTAs, and 10 SAGs combined.

A scene features the song "These Boots are Made for Walking" sung by Nancy Sinatra, daughter of Frank Sinatra. In Ocean's Thirteen (2007) Danny Ocean says "You shook hands with Frank Sinatra." Also, Frank Sinatra played the role of Danny Ocean in the original Ocean's 11 (1960).
The Met event, where the robbery is intended to occur, is an annual gala sponsored and hosted by Anna Wintour, editor-in-chief of fashion magazine Vogue, who plays herself in the movie. Anna Wintour was also the inspiration for Miranda Priestly, the boss of Anne Hathaway in The Devil Wears Prada (2006). The big event that Hathaway went to at the end of that movie was in fact the same Met Gala which would have been sponsored by her boss.
The film cast includes three Oscar winners: Sandra Bullock, Cate Blanchett, and Anne Hathaway; as well as two Oscar nominees: Helena Bonham Carter and Elliott Gould.

Cate Blanchett and Richard Armitage previously worked on the Hobbit trilogy together.
Sandra Bullock appeared with George Clooney (who played Danny Ocean) in Gravity (2013).
