Cold Winter Sun[1] (Spanish: Frío sol de invierno) is a 2004 Spanish drama film directed and written by Pablo Malo [eu] which stars Unax Ugalde and Marisa Paredes alongside Javier Pereira, Marta Etura, Raquel Pérez, and Andrés Gertrúdix.

He crosses paths with Gonzalo, an outcast who has a complicated relationship with his mother Raquel, a hooker.

[2] Cold Winter Sun premiered at the 52nd San Sebastián International Film Festival in September 2004.

[5][11] Nuria Vidal of Fotogramas rated the film 3 of 5 stars deeming it to be a "cold film", "in which the characters live in an absolute loneliness made of strange relationships between each other that gradually unravel".

[12] Casimiro Torreiro of El País described Cold Winter Sun as a crime film displaying "a thick tone and a considerably gloomy look", hampered by the overaccumulation of edgy elements which thereby compromise the verisimilitude of a debut film otherwise promising vis-à-vis its making and the direction of actors.
