Book Club is a 2018 American romantic comedy film directed by Bill Holderman (in his directorial debut), who co-wrote the screenplay with Erin Simms.

The film stars Diane Keaton, Jane Fonda, Candice Bergen, and Mary Steenburgen as four friends who read Fifty Shades of Grey as part of their monthly book club, and subsequently begin to change how they view their personal relationships.

While flying to visit her daughters in Arizona, Diane meets Mitchell and they strike up a relationship – although she is hesitant because her husband died only a year ago and she has not dated in decades.

E. L. James (author of the entire Fifty Shades book series) and her husband Niall Leonard make a cameo appearance as Carol and Bruce's neighbors.

[5] In May 2017, it was announced Diane Keaton, Jane Fonda and Candice Bergen had joined the cast of the film, with Bill Holderman directing, from a screenplay by himself and Erin Simms.

Holderman and Simms also produced the film, along with Andrew Duncan and Alex Saks, the latter two under their June Pictures banner.

[3] In the United States and Canada, the film was released alongside Deadpool 2 and Show Dogs, and was projected to gross around $10 million from 2,781 theaters in its opening weekend.

The website's critical consensus reads, "Book Club only intermittently rises to the level of its impressive veteran cast; fortunately, they're more than enough to bring pedestrian material entertainingly to life.

It was expected that the characters Diane, Vivian, Sharon, Carol, Mitchell, Arthur, Bruce, Jill and Adrianne would all reappear.

[24] In May 2022, Variety announced that the sequel, titled Book Club: The Next Chapter, had begun production with Keaton, Fonda, Bergen, Steenburgen, Garcia, Johnson, and Nelson reprising their roles from the first film.
