Unfairly neglected since its original low-key cinema run, Secret Friends is the only feature to be written and directed by Dennis Potter (Pennies from Heaven, The Singing Detective).Made shortly after his hugely controversial mini-series Blackeyes, the film centres on a writer, played by Alan Bates (A Day in the Death of Joe Egg), who descends into a kind of madness during a train journey as memories, fantasies and psychotic visions collide.Extras:High Definition remasterOriginal stereo audioKeeping Secrets (2020, 10 mins): an analysis of Potter's film by Graham Fuller, editor of Potter on PotterBon Vivant (2020): actor Ian McNeice recalls working with Dennis PotterTheatrical trailerImage gallery: publicity and promotional materialNew and improved English subtitles for the deaf and hard-of-hearingLimited edition exclusive 36-page booklet with a new essay by Jeff Billington, Dennis Potter on the making of Secret Friends, an extract from Potter on Potter, an overview of critical response
