Beltrán pursued his studies in Barcelona, which included a four-year humanities course at Pompeu Fabra University. He later studied dramatic arts, dance-theatre course (with Montserrat Prats) and acting (with Raimón Molins). He also had a short radio course with Radio Estudi Esplugues.
Beltrán has been involved with plays such as Alan Bennett's History Boys, and with Little Ashes which went from theatre to the big screen. According to him, that film was his first job in cinema, and in fact the end of his course coincided with the casting for the film.
