Eternal Family is a 1997 OVA directed by Koji Morimoto and released by Japanese animation studio, Studio 4°C. The film is about the daily life of a group of six very different strangers who, for scientific purposes, are brainwashed into believing that they are a family. The family is filmed and to recoup scientific expenses the distribution rights for the footage are sold to a television station for broadcast as a domestic soap opera called Eternal Family. The show becomes highly popular in the outside world so when a plumbing disaster results in the family accidentally escaping, the television station and the residents of Champon City spare no expense to retrieve them.
The story was written jointly by Morimoto and Dai Sato. Eternal Family represents Sato's debut as an anime screenwriter, and Morimoto's first foray into the field of broadcast media. In 2004 the OVA was collected for release on one DVD.
