Twenty years after his death, this new documentary reveals never-before-seen footage of one of the country's most popular comedy stars: Frankie Howerd.

Alongside clips from his classic shows, the programme unveils professional and personal archive film and audio that has never been broadcast. From pilots and home movie footage to unseen interviews and material from his live stand up show, the show shines a light on the highs and lows of comedy legend Frankie's remarkable career.

The film also lifts the lid on Frankie's vast collection of personal correspondence. From Sir Laurence Olivier and Paul McCartney to Howerd's many fans, everyone wrote to Frankie, and Frankie always took the time to write back.

The documentary features a range of contributors, including some of the comedian's most famous fans, such as Sir Bruce Forsyth and Barry Cryer. It also hears from the people who were closest to him, such as his former agents, collaborators and writers, including Ray Galton, Alan Simpson and Clive Anderson.
