A Bright Sun (Catalan: Un sol radiant)[1] is a 2023 Spanish apocalyptic coming-of-age drama film directed by Mònica Cambra and Ariadna Fortuny.

It stars Laia Artigas, Nunu Sales, Núria Prims, and Jaume Villalta.

The plot depicts how 11-year-old Mila faces her last days before the end of the world.

[1] An Atiende Films production,[3] the film was born out as a final degree project of five Pompeu Fabra University alumni (Mònica Cambra, Ariadna Fortuny, Clàudia Garcia de Dios, Lucía Herrera, and Mònica Tort).

Rubén Romero Santos of Cinemanía rated the film 4 out of 5 stars, writing that "Carla Simón's haptic delicacy and Lars von Trier's unredeemed nihilism" are surprisingly combined in the film.
