Perfect Day is a two-hour comic television-movie, initially broadcast on Channel 5 in December 2005. The first installation followed a group of university mates who come together for the wedding of Tom and Amy. Along the way, old loves are rekindled and new one alight.

The film was well received, both by viewers, drawing some of the channel's highest figures, and by critics. So successful was it in fact that it spawned both a prequel, Perfect Day:The Millennium, which told the story of the characters getting together for a party on New Year's Eve 1999, and a sequel, Perfect Day:The Funeral, in which the characters reunite one year after the wedding following the death of one of the group.

Josephine plays Rachel, an old flame of goofy Rob (Bruce Mackinnon) reignited over the course of the wedding weekend.
