David Trueba directs this biography nominated for 11 Goya awards and finally deservedly winner of the Goya for best actor, David Verdaguer, narrated in a tone of romantic drama sprinkled with the humor of his jokes, the life of comedian Eugenio during the sixties and seventies . Particularly focusing on the years that he shared life with his wife Conchita. It begins in the late 60s, Eugenio (David Vergader) is a young jeweler who falls in love with Conchita (Carolina Yuste) and the two form a musical duo. When she left music, he began as a comedian and over time became one of the most important comedians in Spain.The title of the film "Saben aquell" addresses how Eugenio started the jokes on him: "You know what...". Eugenio, who is not overtly mentioned in the film, collected around 15,000 different jokes for his live performances. Most of them were recorded and compiled on cassettes for sale. As Trueba, also co-writer with Alberto Espinosa, explains, this is a film about humor and survival. Eugenio was one of the most popular comedians of the Spanish Transition. Everything about his physical appearance and appearance showed that he was at odds with humor: a very serious man, without gestures, perpetrated through smoked glasses and a black shirt, with a smoking cigarette behind a microphone, but despite all these inconveniences would achieve great success, becoming him the culprit of making an entire country laugh. This film 'You know that' tries to establish the answers of this great comedian, answering the question: What was hiding inside him?At the same time, we are given brief panorama of life in the sixties and seventies, during the Franco regime and the social or economic limitations in which people lived at that time and evoking the death of Francisco Franco.
