Javier Bardem

Bardem was born on 1 March 1969 in Las Palmas de Gran Canaria, in the Canary Islands, Spain. His mother, Pilar Bardem (1939–2021), was an actress, and his father, José Carlos Encinas Doussinague (1931–1995), was the son of a cattle rancher. According to Pilar's memoirs, José had a "capricious and violent will," and shot up the front door. He changed jobs more than 10 times, leading to evictions and the children going hungry. The two separated shortly after Javier's birth. His mother raised him and his elder siblings, Carlos and Mónica, alone (another sibling died shortly after birth), both of whom have also pursued an acting career. His father died of leukemia in 1995.

Bardem comes from a long line of filmmakers and actors dating back to the earliest days of Spanish cinema. He is a grandson of actors Rafael Bardem and Matilde Muñoz Sampedro (sister of actresses Mercedes and Guadalupe), and a nephew of screenwriter and director Juan Antonio Bardem. On the latter's side, he is a cousin of filmmaker Miguel Bardem. His uncle Juan Antonio was imprisoned by the Franco regime for his anti-fascist films. Bardem was brought up in the Roman Catholic faith by his grandmother.

As a child, he spent time at theatres and on film sets. In 1974, he made his first television appearance, in Fernando Fernán Gómez's television series El pícaro (The Scoundrel). He also played rugby for the junior Spanish National Team. Though he grew up in a family full of actors, Bardem did not see himself going into the family business, and painting was his preferred medium. He went on to study painting for four years at Madrid's Escuela de Artes y oficios. In need of money, he took acting jobs to support his painting but felt he was a bad painter and eventually abandoned it as a career.

In 1989, for the Spanish comedy show El Día Por Delante (The Day Ahead), he had to wear a Superman costume for a comedic sketch, a job that made him question whether he wanted to be an actor at all. Bardem also worked as a stripper (for one day) during his struggling acting career.
