The Fifty Shades of Grey [1] novels have not only spawned a mega-successful film franchise [2] and a new appreciation for Jamie Dornan's half-naked body [3], but also BDSM-loving book clubs everywhere. The latter group is the subject of the upcoming romantic comedy Book Club, which stars Jane Fonda as a woman who introduces her three friends — Diane Keaton [4], Candice Bergen, and Mary Steenburgen — to E.L. James's debut novel. While none of them go on to fall in love with emotionally guarded, billionaire orphans, the book does inspire them to find romance in a few unexpected ways. Watch the trailer before it opens in theaters on May 18!
