Of the film's two story-lines, director Cherie Nowlan said: ''They are the two stories which are the flipside of each other and together make a unique and interesting whole. The worlds look and feel different in obvious, appropriate ways. Guy and Jenny's story is set throughout the '80s. Guy and Lizzie's story is set in 1995. One is a wealthy, privileged world. The other ranges from a living wage existence to a more comfortable, middle-class life. Everything about Guy and Jenny's world is casual and temporary. Everything about Guy and Lizzie's world is formal and setting-in-concrete throughout the film.''
Around a dozen cast and crew personnel worked on both this picture and director Cherie Nowlan's recent previous short film Lucinda, 31 (1995). These included actress Jane Turner, cinematographer Kathryn Milliss, writer Alexandra Long, assistant director John Martin, production designer Clarissa Patterson and four guys from the sound department.
The Jenny story in the film is a memory. Director Cherie Nowlan describes it as an experience crystallized in time.
The film's original Australian title of ''Thank God He Met Lizzie'' was changed to ''The Wedding Party'' for the picture's American release stateside in the USA.
