El crimen de Pepe Conde (1946) as Flamenco bar customer

¡¡Campeones!! (1943) as Man at the party in the bar

Gritos en la noche (1962) as Nightclub customer

Las muchachas de azul (1957) in dual roles, wearing the same suit, as a Department store customer and a Restaurant customer

La reina del Tabarín (1960) as Nightclub customer at New Year.

Despite this only being a background role, you do have Enrique Núñez who is credited in an identical role, so there may be a small possibility that he could be too.

Teatro Apolo (1950) as Friend of Miguel.

This is a quite substantial role, always in the background but appearing in around 6 scenes, but sadly it does not seem like he is credited.

Sangue en el ruedo (1969) as Bullfight spectator

Segretissimo (1967) as Plane passenger.

Mostly hidden behind the seat, but identifiable from his rather unique glasses.

No es bueno que el hombre esté solo (1973) as Man at the memorial

La guerra empieza en Cuba (1957) seen both as a Party guest and a Guest at the ball, which may or may not be considered the same role (neither seen too clearly in the poor quality copies available)
