The apparent suicide of an eminent psychologist prompts his teenage daughter (Pamela Franklin – The Prime of Miss Jean Brodie, The Legend of Hell House) and one of his patients (Stephen Boyd – Ben-Hur, Fantastic Voyage) to investigate. Convinced he was murdered, the two begin a journey into the lives and twisted psychoses of the doctor’s disturbed patients.Directed by the great Charles Crichton (Dead of Night, The Lavender Hill Mob, A Fish Called Wanda), stunningly photographed by Douglas Slocombe (The Italian Job, Raiders of the Lost Ark), and starring an incredible cast which includes Jack Hawkins, Richard Attenborough, Diane Cilento and Judi Dench in one of her earliest screen roles, The Third Secret is a dark and elegant psychological thriller which has long been overlooked, but is now ripe for rediscovery.Extras: INDICATOR STANDARD EDITION SPECIAL FEATURES• High Definition remaster • Original mono audio • Audio commentary with film historians Dean Brandum and Eloise Ross • The BEHP Interview with Charles Crichton (1988, 103 mins): an archival audio recording, made as part of the British Entertainment History Project, featuring the celebrated filmmaker in conversation with Sidney Cole • The BEHP Interview with Douglas Slocombe – Part One, The Early Years (1988, 103 mins): an archival audio recording, made as part of the British Entertainment History Project, featuring the renowned cinematographer in conversation with Sidney Cole • Crichton on Crichton (2019, 8 mins): a personal account by third assistant director David Crichton of working on his father’s film • An Unconscionable Thing (2019, 5 mins): second assistant director Kits Browning recalls the making of The Third Secret • Mr Slocombe’s Mattress (2019, 7 mins): focus puller Robin Vidgeon discusses the work of Douglas Slocombe • Lost Souls (2019, 23 mins): an in-depth appreciation by author and film historian Neil Sinyard • Theatrical trailer • Image gallery: on-set and promotional photography • New and improved English subtitles for the deaf and hard of hearing
