This was the fourth and last "Murder, She Wrote" movie of the week that CBS Television/Les Moonvies negotiated with Peter and Angela Shaw, "Corymore Productions", fulfilling the negotiated settlement canceling the very popular series in 1996. The original Cabot Cove (Mendocino, California series location) never was considered for use as a basis of a story plot in any of the projected four MOW projects. Peter and Angela wished to close the show-series occurring in Ireland. During the twelve years of the CBS series, many story plots, scenarios, had been set in Ireland. Set in Ireland, second unit filming always was organized to film establishing exterior buildings, landscapes, an automobile driving on country lanes with matching vehicles filmed in conjunction of the film's local Los Angeles exteriors. This last project gave an excuse for Angela and Peter to film the Ireland inserted establishing shots after filming was completed at Universal Studios. After these exterior Ireland street establishing insert shots were completed, the editors completed and delivered the finished two hour special to CBS. Filmed during 2002, the last "Murder, She Wrote" aired in 2003, after Peter Shaw's death in January 29, 2003. The film was dedicated as a memorial to Peter Shaw Pullen.

Two joggers, who discover Nora's body prone under the thicket of the trail's overgrown bushes, introduce the discovery scene. The male jogger is Angela and Peter Shaw's grandson, Peter John Shaw (b.1982), Anthony and Lee Shaw's first born.

The way the testament was made was taken from The Last Gentleman (1934).

While the film is set in Ireland, the Garda (police) cars have Northern Irish registration plates (PIB XXX).
