Caché (marketed as Hidden in English) is a 2005 French-language film, written and directed by Austrian filmmaker Michael Haneke. It stars Daniel Auteuil as Georges, and Juliette Binoche as Anne. It is the first film where Haneke uses High Definition video cameras. During a press conference at the Cannes film festival he expressed the now famous quote: I always say that a feature film is twenty-four lies per second; the lies may be told to serve a higher truth, but they aren't always.

Georges is a successful TV presenter and he lives what seems to be a good life with his wife Anne and his son Pierrot. Anne is a book publisher, and Pierrot seems to be a well adjusted 12-year-old boy. But some mysterious videotapes start showing up on their doorstep. At first, the tapes seem totally harmless, perhaps made by a fan. But when some videos are strangely accompanied by bloody drawings in the style of an adult imitating a kid, it suggests that they are more than just inoffensive jokes. Little by little, the tapes reveal that whoever is making them knows more about George's past than he would like them to.

They then contact the police, but, since there has not been an open threat, the police offer no help. A videotape leads Georges to the modest apartment of an Algerian man his own age. It is Majid, whose parents worked for Georges' family back in 1961. He refuses to share this knowledge with Anne. This drives a deep wedge between husband and wife. The son feels the estrangement between his parents. He reacts by staying out all night without telling his parents where he is. The parents reacts with panic, believing he may be kidnapped by Majid. Georges and Anne have Majid and his teenage son arrested.

This leads to some brutal confrontations when the police doesn't find any evidence linking Majid or his son to the "kidnapping".

Caché premiered at the 2005 Cannes film festival. The film won numerous awards during its succesful run at the festival, including the prize for Best Director, and the FIPRESCI prize. Many critics saw Caché as a strong contender for the Palme d'Or that year. The film also won the Prize of the Ecumenical Jury. The film also won several awards at the European Film Awards, including "Best European Film 2005". As evidenced from the IMDB boards, many people have debated the open ending of the film.

Deborah Young from Variety stated that: The tight pacing of Michael Hudecek and Nadine Muse's editing keeps the story fluid and focused but very concise, commanding audience attention from start to finish.

Kirk Honeycutt at the Hollywood Observer stated that: In unraveling a nearly forgotten secret in the life of a self-satisfied and smug French intellectual, Haneke probes deeply into issues involving guilt, communication and willful amnesia.

Donald J. Levit from Reeltalk Movie Reviews wrote: The film's frequent long takes are painful both on the eye and on the plot.
