Free Agents star Stephen Mangan landed the lead role in the Norman Conquest plays at the Old Vic just as the green light for this sitcom was given. As a result, the production team had to arrange filming around his schedule.
Filming started every day at 7.30am and Mangan went without lunch breaks so he could dash off at 5pm to perform in the theatre.
Pascal Langdale played a character nicknamed 'Dr Two Scenes' in Episode 1.5... named as such because the actor only ever appeared in two scenes in the medical drama he 'starred' in. Langdale in real life has appeared in one episode of Doctors, Casualty and Holby City.
