Asier Etxeandía studied acting at a Biscayan school, of which he only keeps fond memories of two teachers, Eguzki Zubia and Juan Carlos Garaizabal.

The Globomedia production company hired him during the first season of One Step Ahead, where he played Beni, a homosexual who entered an arts academy with the hope of becoming an actor.

In spite of everything, he recognized that his work there opened doors for him and he met his first friends in the capital, including Natalia Millán.

[2] Natalia Millán thought of him to star in the musical Cabaret offering him the role of Master of Ceremonies, the one in charge of commenting ironically on the events that take place in Germany in the 1930s .

He was cast in Pedro Almodóvar's Broken Embraces, playing a small role as a blind waiter, which was not included in the final cut, but whose scene is part of the additional content of the film on DVD.
