Her film Absent from Our Own Wedding tells the remarkable story of retired husband and wife team Tom and Teresa Kennedy, who conduct about 500 weddings a year for a fee of $750, without ever meeting a blushing bride or a gallant groom.
Award-winning British documentary maker and former actor Debbie Howard recently released the first film about an American duo who run a thriving proxy marriage business from their rural home in Flathead, Montana.
Teresa, 56, regularly stands in for either the bride or the groom, who can be same-sex, while a colleague steps up to play their intended.
But marriages in which neither the bride nor the groom are present happen all the time, and not only in countries with very different customs and laws to Britain.
