Wedding Days is a British documentary which was first broadcast on Channel 4 in 2006 with a really interest concept. The filmmakers found the weddings page of an old copy of the Brighton and Hove Gazette from a day in August 1980, selecting one day and one page.
They tracked down twenty of the couples who had their wedding photos and information published on that page to ask them on film happened to their marriage in the intervening 25 year period (to 2005 when filmed). The resulting film is a unique perspective of marriage over a quarter of a century, the couples experience of marriage were very mixed with some marriages working out and some not. The people featured had various different perspectives on marriage in general and on their specific marriage, both successful and failed.
