In season two, Dawn Steele, Alexander Morton and Hamish Clark were bumped up to star status having been supporting regulars in the first season.  Briers and Pilkington left the show in season three, prompting Julian Fellowes to receive star billing having appeared as recurring guest in seasons one to four.  In season five, Fellowes and Mackenzie left the show, with Lloyd Owen filling the void as Archie's estranged half-brother, Paul.

Simone Lahbib and Tom Baker also joined the series six cast as Paul's love interest and Hector's younger brother, respectively.  Lahbib left the show the following season due to pregnancy and Kirsty Mitchell was brought in as Paul's new love interest.  Kellyanne Farquhar was the final actor to gain star billing, joining the cast as Paul's wayward god-daughter.  The show ended in 2005 with special guest appearances by Briers, Clark and Fellowes.
