Documentaries, reconstructions, interviews, etc.
★ The London Nobody Knows (1967)
James Mason takes a wander around some of London's weirder corners, including 29 Hanbury Street where Annie Chapman's body was found. DAILYMOTION LINK (38:02).
★ Jack the Ripper (1973)
Fictional Detective Chief Superintendents Barlow and Watt (of Z-Cars and Barlow at large fame) reopen the case. They talk through the evidence and the existing theories, interspersed with docudrama style scenes set in the 19th century. The series has six episodes and is probably my favourite JTR documentary.
