The organizers of the Cannes Film Festival have unveiled the official poster for this year's edition. It features a scene from the late Japanese director Kurosawa Akira's movie based on the atomic bombing of Nagasaki.

The film, "Rhapsody in August," was presented out of competition in Cannes in 1991.

The organizers say the movie follows a grandmother, a survivor of the atomic bombing on August 9, 1945, who "passes on her faith in love and integrity as a bulwark against war to her grandchildren and her American nephew, with tenderness and contemplation."

The poster shows the grandmother sitting alongside her four grandchildren, looking into the distance. Ahead of them, the festival's palm symbol can be seen floating in the sky, casting a light over the scene.

French media say the poster is a call on people to unite amid the current tense geopolitical situation in the Middle East, Ukraine and elsewhere in the world.

Cannes is one of the world's three major international film festivals. It will run from May 14 through 25.
