Berger attended primary and secondary school in Artxanda Trueba, located on the outskirts of Bilbao, Spain.

In 1988 he directed his first short film, Mamá (Mum), with artistic director Álex de la Iglesia and Ramon Barea.

Thereafter, he began a parallel career as a publicist and producer of music, culminating in 2003 with his first film Torremolinos 73,[1] with Javier Cámara, Fernando Tejero and Candela Peña.

Torremolinos 73 received four Goya nominations and won Berger the Golden Biznaga at the Málaga Film Festival, as well as multiple national and international prizes.

In 2024, Berger was nominated for the Academy Award for Best Animated Feature for Robot Dreams, but lost to Hayao Miyazaki's The Boy and the Heron.
