His Master's Voice (Spanish: La voz de su amo) is a 2001 Spanish crime thriller film directed and written by Emilio Martínez Lázaro, and starring Eduard Fernández, Silvia Abascal, Joaquim de Almeida, and Imanol Arias.

[1] It follows Charli, a former ETA member and football player now working as chauffeur and bodyguard for shady businessman Oliveira and having a casual relationship with substance addict Katy.

After an ETA lorry bomb attack in the wake of Oliveira's refusal to bow to the ETA extortion racket, Charli is tasked to protect Oliveira's daughter Marta, having sex and then starting to fall romantically for her.

[4] Jonathan Holland of Variety deemed the film to be "an intelligent, upbeat thriller that welds an invented storyline onto a factual background" and "manages to suggest the moral and political complexity of the subject without sensationalizing it".

[2] Ángel Fernández-Santos of El País considered that the film is, above all, "an act of maturity and solvency, a highly professional work that has led to the elaboration of an admirably measured thriller".
