Ariadna Gil i Giner (born Barcelona, Spain; January 231969) is a Spanish actress. She is known for her expressive acting in films like Belle Epoque or Lagrimas Negras

Bigas Luna discovered her for the 1986 movie "Lola". After 4 films in Catalan, she took part in a movie in Spanish in 1991, Emilio Martínez Lázaro's "Amo tu cama rica" 1991.

From 1993 to 2007, she has performed in more than 31 films, like "Libertarias", directed by Vicente Aranda; "El laberinto del fauno", by Guillermo del Toro or "Soldados de Salamina", directed by her husband David Trueba.

Born in January, 1969, daughter of a prestigious lawyer, she grew up studying singing, dancing and the violin. She even appeared occasionally singing with her two brothers in a group called "Matamala" ("Bad Kill"). At 17 she appeared on the cover of an avant-garde Catalonian magazine, and from there she began working in local theatre companies and later on local Catalonian TV channels, including giving Spanish language classes on Canal 33. It was here she caught the eye of Bigas Luna, which led to Luna, her first film, and thus her future was set. It was in 1991 that she became well known in the film Amo tu Cama Rica, a comedy with Javier Bardem, consolidated a year later in Fernando Trueba's romantic comedy Belle Époque, starring Penélope Cruz. However her better and more serious roles appeared from the mid-nineties onwards, and she showed she was able to take on the most difficult parts, most notably in Malena es un Nombre de Tango and Lágrimas Negras. She also had time to do a few theatre productions in Catalonia, such as Chekhov's "The Seagull," among other plays. She has a daughter, Violeta, named after her character in Belle Époque, born from her romance with the scenery-maker and also director David Trueba, brother of Fernando. She is extremely interested in working in Iberamerican cinema and has already worked in Argentina. To date she has shown she is an extremely versatile actress, such that she is known here in Spain as the actress for "impossible roles." Much now depends on whether she can be offered the right parts so that she can continue to develop as a serious character actress.
