Operation Good Guys (OGG) is a 1997 British mockumentary, a fly-on-the-wall documentary series about an elite police unit's bid to snare one of Britain's most powerful crime lords. But things are not quite what they seem... Operation Good Guys is in fact an innovative and irreverent comedy. Blurring the line between fact and fiction, it witnesses, on camera, the total breakdown, professionally and personally, of the Operation Good Guys team. Throughout the operation, The 'Good Guys' have an unfortunate habit of embroiling into their calamitous world some of the country's best-known celebrities, from actors and footballers, to TV presenters and even the odd ex-convict.

It was written by Ray Burdis, Hugo Blick and Dominic Anciano, although the majority of dialogue was improvised by the actors.

The actors involved include:

David Gillespie as D.I. Beach, with D.S. Raymond Ash (Ray Burdis), Sgt Dominic de Sade (Dominic Anciano), Kim Finch, alias "Boo Boo" (Kim Taylforth; series 1 only), "Bones" (Perry Benson), Gary Barwick (Gary Beadle; series 1 and episodes 1 and 4 of series 2 only), "Strings" (John Beckett), Mark Kemp (Mark Burdis), accountant Roy Leyton (Roy Smiles; series 1 only), Bill Zeebub (William Scully, QGM, present in the first series as a background character; brought to the fore more in series two and three), and Hugo Blick (Smiler McCarthy (series 1) & Narrator (series two and three)).

There were three series produced, which featured guest stars including David Seaman, Jude Law, Sean Pertwee, Jonny Lee Miller, gangster 'Mad' Frankie Fraser, ex Spandau Ballet star Martin Kemp, Denise van Outen and Donna Air.

In some ways, although generally more far fetched (particularly in the second and third series), the show, with its spoof documentary format, pompous lead character (DI Beach) and improvised acting can be seen as a precursor to The Office.

The second and third series included a laugh track, which some felt somewhat spoilt the "mockumentary" feel.

The three series were released on VHS in the early 2000s. In 2005, the three series of OGG were finally released on DVD format. In addition to the original episodes, the three disc DVD boxset includes some extras including a brand new episode, 'Where Are They Now?'. This new material addresses the subject of what happened to the team after they were sacked from the Police force at the end of series three. Original co-writer, Dominic Anciano, played no part in 'Where Are They Now?'. His character, Sgt. Dominic de Sade, was apparently last seen after seizing the money from a multi-million pound robbery. With Anciano apparently uninterested in creating new OGG material, another series looks unlikely.

All of the dialogue is improvised by members of the cast.
