Juan Carlos Fresnadillo (born December 5, 1967 in Santa Cruz de Tenerife, Canary Islands) is an Academy Award-nominated Spanish film director, script writer, and producer. He directed Intacto and 28 Weeks Later, the sequel to Danny Boyle's 28 Days Later.
In 1985, Fresnadillo moved to Madrid. He started out in photography and cinema studies and then began his career in short films. In 1987, he set up a production company, which produced several short films and commercials. Fresnadillo went on to become a production assistant for Gustavo Fuertes' short film El juicio final (1991) (US title The Final Judgement 1991).
In 1996, he had his debut with the black-and-white short film Esposados (US title: Linked), for which he was also the executive producer. The black comedy tells the story of a couple who are constantly fighting over money; when they find themselves winning the Christmas lottery, however, they have such different ideas about what to do next that the husband tries to get rid of his wife. Esposados won 40 national and international awards. It was also nominated for an "Oscar" for Best Short Film in the same year, making Fresnadillo an overnight star in Spain.
