One star that can’t be missed at Cannes this year is Ingrid Bergman, who is quite literally the poster girl for the festival.

The late actresses’ youthful image is plastered all over town, including several gigantic billboards that overlook the grounds. In addition, special screenings of her classic films have run in theaters throughout the week.

Isabella Rossellini, 62, Bergman’s daughter and jury president of the Un Certain Regard Competition, and her daughter, Elettra Wiedemann, spoke to PEOPLE about the impact their family matriarch had on her loved ones and the legacy of film.

“She is everywhere,” Rossellini says of her mother. “She is the official poster of the festival and she has enormous spread all over Cannes. It’s wonderful”

Seeing her Bergman’s image was “very emotional” for the actress’ daughter, who says “the size [of the poster] surprised me, and the fact that’s she’s everywhere, in every shop.” “She’s like a big angel over Cannes,” Bergman’s granddaughter, 31, adds.

Rossellini, who presented a documentary about her mother called Ingrid Bergman – In Her Own Words at the festival on Tuesday, says Bergman “kept everything, she kept diaries and she kept letters” detailing her life.

When she asked her mom why she held on to the mementos, Bergman answered, “Because I think my life is important as an artist.”

While Rossellini says Bergman was always a humble woman, she recognized that her career in film would one day be of interest to future generations curious about the history of cinema.

“Of course at the time in ’82 when she died there weren’t any film archives,” Rossellini explains. “There weren’t film restoration. So she has been, if you want, one of the first people to see films as an art form.”
