The series was ranked number 34 in a poll for Britain's Best Sitcom.

Detective Constable Robert Kray, played by Kevin Allen in series 1, was replaced in series 2 by Detective Constable Gary Boyle, played by Mark Addy.

Creator and writer Ben Elton was a fan of Dad's Army, and many of the characters were influenced by that show, such as Fowler and Grim's relationship mirroring Captain Mainwaring and Warden Hodges, and Constable Goody being a 'stupid boy' akin to Private Pike.

Constable Gladstone's habit of interrupting briefings with stories about life in Trinidad echoes Lance Corporal Jones's tendency to reminisce about Sudan during Captain Mainwaring's speeches in Dad's Army.

In the episode 'Rag Week', Fowler is briefly seen walking out of a shop called 'Mainwaring's', a nod to Dad's Army.

Writer Ben Elton appeared in the show himself, playing a homeless man in the Christmas special episode 'Yuletide Spirit'.

In the first series, the 'wanted' poster behind Fowler's desk in the briefing room is actually an E-FIT image of Ben Elton.

The Region 1 (North America) DVD release features series 2 episodes cut to fit a roughly 30-minute runtime, and the first series episodes are not presented in original broadcast order on either the Region 1 or Region 2 releases.
