The idea for And Mrs feels like it was hatched after somebody stumbled upon the word necrogamy during a Wikipedia search. Necrogamy is a marriage in which one of the engaged is dead and was originally intended to provide financial support for war widows. First-time feature director Daniel Reisinger aims to use necrogamy as a unique way of exploring the idea of overcoming grief, with Aisling Bea playing a Londoner who decides to proceed with her wedding despite the untimely death of her fianc (Colin Hanks).
