It is partly based on Theodore H. White's Life magazine interview with the widow at Hyannis Port, Massachusetts, in November 1963.

Members of the White House close to the newly sworn-in president Lyndon B. Johnson and his wife Lady Bird are seen comforting Jackie in the aftermath aboard Air Force One.

Robert, along with President Johnson, Lady Bird, and members of the White House, witness the murder of Lee Harvey Oswald by Jack Ruby on live television.

After John F. Kennedy Jr.'s third birthday, Robert voices his fears to Jackie that her husband's short time as president will not be noted by future generations.

The film concludes with Jackie having her miscarried and stillborn children's coffins being re-interred next to her husband's grave at Arlington National Cemetery in Virginia.

A number of other historical figures are depicted in minor and non-speaking roles: Admiral George Burkley (Peter Hudson), Dr. John Walsh (John Paval), Judge Sarah T. Hughes (Vivienne Vermes), Governor John Connally (Craig Sechler), Nellie Connally (Rebecca Compton), John Metzler (David DeBoy), Charles Collingwood (Stéphane Höhn), Charles de Gaulle (Serge Onteniente), Pablo Casals (Roland Pidoux), Robert McNamara (Emmanuel Herault), Hugh Auchincloss (William Beaux d'Albenas), James C. Auchincloss (Nicolas Guigou), Jack Brooks (David Friszman), Toni Bradlee (Chloé Berthier), Benjamin Bradlee (Éric Soubelet), Ted Kennedy (Gaspard Koenig), Joan Kennedy (Mathilde Ripley), Pat Kennedy (Barbara Foliot), Peter Lawford (Albain Venzo), Eunice Kennedy (Frédérique Adler), Sargent Shriver (Patrick Hamel).

The film's script, written by Noah Oppenheim, was conceived as an HBO miniseries, covering the "four days between John F. Kennedy's assassination and his burial, showing Jackie at both her most vulnerable and her most graceful".

"[13] Oppenheim said that the screenplay itself did not change much over the long development process, revealing, "When Pablo Larraín boarded the project, he had ideas.

"[14] In April 2010, it was announced that Rachel Weisz would star in the titular role, with Darren Aronofsky set to direct and produce the film, from Oppenheim's script.

[26] Her primary source was the seven-part eight-and-a-half-hour Life magazine interview conducted in the early part of 1964, by Arthur M. Schlesinger Jr. with Kennedy.

Portman trained with dialect coach Tanya Blumstein, and in the beginning, had difficulty with copying Kennedy's vocals, especially on the first day of set when her initial delivery was too much.

[31] Portman is one of many actors to have portrayed Kennedy in cinema and on television, following Divine, Jaclyn Smith, Sarah Michelle Gellar, Roma Downey, Jill Hennessy, Joanne Whalley, Kat Steffens, Jacqueline Bisset, Jeanne Tripplehorn, Parker Posey, Blair Brown, Katie Holmes, Victoria Beckham, Ginnifer Goodwin, Stephanie Romanov and Minka Kelly.

After failing to find one in New York, Los Angeles, London, and Paris, Snodgrass began searching in northern Europe and found Danish actor Caspar Phillipson.

[33] Principal photography on the film began in December 2015 in the Paris-area studio Cité du Cinéma, where most of the interior scenes were shot.

The site's critical consensus reads, "Jackie offers an alluring peek into a beloved American public figure's private world — and an enthralling starring performance from Natalie Portman in the bargain.

"[53] Guy Lodge of Variety also gave the film a highly positive review, writing that "Chilean helmer Pablo Larraín makes an extraordinary English-lingo debut with this daring, many-leveled portrait of history's favorite First Lady.

[55] The Dallas Morning News commentator Anna Parks criticized the film's negative portrayal of Jackie's relationship with Lyndon and Lady Bird Johnson.
