In the mid-2000s, there was a marked increase in the number of films and TV shows taking a look back at the dark days of football hooliganism in Britain.
Danny Dyer's football casuals flick The Football Factory (2004) was followed a year later by Green Street starring Elijah Wood.
In 2006, TV channel Bravo capitalised on this wave of interest by enlisting Danny Dyer to present a new series called Danny Dyer's Real Football Factories - and it proved to be a huge hit.
