Perfect Day was a two hour television movie, initially broadcast on Five in December, 2005.

Centered around a group of university friends who reunite five years later for the wedding of Tom and Amy, it tells the story of old loves rekindled, marriages falling apart and the problems of career women finding love. It also starred Aidan McArdle, Kate Ashfield, Rhashan Stone, Claire Keelan, Bruce Mackinnon and Chris Bisson.

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.

In November, 2006 when the prequel and sequel were broadcast the initial film was retitled Perfect Day:The Wedding and the three programmes were broadcast in chronological order.
