Sevilla made his television debut with Barrio Sésamo when he was 34 years old. He continued with the role until 1987, when the series was cancelled. Though his screen career was limited in the subsequent years, Sevilla reappeared in the 1997 Catalan production Primats. Since then, he began working more frequently, first in TV movies (Pirata, 1999) and then in mainstream productions, including a small role in the comedy No respires: El amor está en el aire, with Leonor Watling, and a starring role in Jaume Balagueró's The Nameless (both 1999). He also appeared as a guest in prestigious Spanish TV series Compañeros and El Comisario.
