Earlier today Jessica Chastain joined to Penelope Cruz, Marion Cotillard, Lupita Nyong’o and Fan Bingbing at the 2018 Cannes Film Festival to promote their upcoming spy thriller 355. Alongside director Simon?Kinberg they attended a presentation at the Majestic Hotel — easily the most glamorous event thus far at this year’s otherwise sleepy Cannes. Festival glitz typically takes place on a red carpet and involves a finished film. Such was not the case with the 355 presentation, whose collective star power easily eclipsed any other event of the festival to date.

Adding to the intrigue, the five women were transported by boat to a photo op near the famed Hotel du Cap. After the presentation, Chastain, who is producing the film, headed to a lunch reception at the Majestic, sponsored by The Hollywood Reporter and DirecTV on the Grey Goose Terrace.

Sources say the film’s budget will exceed $75 million, making it one of the priciest Cannes market titles of all time. Chastain, who served as a Cannes juror last year, was disheartened by the female representations in the films she screened. So, she handpicked and enlisted Fan, Cotillard, Cruz and Nyong’o — “Luckily they all said yes,” Chastain told the buyers — as well as her X-Men: Dark Phoenix director Kinberg.

There’s no script yet, but according to Vanity Fair’s Rebecca Keegan, who accidently was allowed into the no-press, top-secret presentation before she was kicked out while live tweeting, the plot revolves around five spies from agencies around the world who form their own team, dubbed 355. Theresa Rebeck (Catwoman) is writing the screenplay.
