Feature-length documentary looking at the wild success of the On The Buses film series.

Debuting on ITV in 1969, sitcom On The Buses ran for 74 episodes over seven series, until 1973.

Its small screen popularity was such that horror producers Hammer Films took their first steps into the comedy genre by making a feature film in 1971. Produced for less than £100,000, it took more than £1 million at the box office in just six weeks, ensuring not one but two sequel features in the following two years.

Fifty years since the release of the first silver-screen spin-off, all three films remain wildly popular and are repeated regularly on television. Featuring never-before-seen interviews with members of the cast and crew, this documentary examines their success and tells their full story.
