The film, which adapts Penelope Lively's tale of a widow who opens a book store in a small town, took home the prizes for best film, best director and best adapted screenplay. It is only the second time an English language film has been named best picture - with Coixet making it a double after 2006's The Secret Life Of Words.
Also winning multiple prizes on the night was Basque film Giant (Handia), directed by Aitor Arrewgi and Jon Garano, which picked up awards for Javier Agirre Erauso's cinematography, Pascal Gaigne's score and a new actor performance award for Eneko Sagardoy as the titular character among a host of other technical gongs.
The best first feature went to Carla Simon's autobiographical Summer 1993 (Estiu 1993) - Spain's foreign language Oscar nominee. It also scooped two acting prizes - best supporting actor for David Verdaguer and the new actress award for Bruna Cusi, who play an uncle and aunt who adopt their young niece after the death of her mum from AIDS complications.
Javier Gutiérrez was named best actor for his turn as a frustrated wannabe writer in The Motive (El Autor), while Adelfa Calvo won the supporting actress prize for her scene-stealing turn as a gossipy building supervisor in the same film. Nathalie Poza was named best actress for Can't Say Goodbye (No Se Decir Adios).
