Today (1968) was a genuine live Thames Television local news/discussion programme fronted by Bill Grundy; it was on this show, in the Wednesday 1st December 1976 edition, that Sex Pistols had their infamous "Filth and the Fury" encounter with the presenter (for which he was suspended).
In the film Mildreds maiden name is revealed as Asquith whilst in the TV series it is Tremble.
The central location in the film is that of the Edwardian houses on Myddleton Terrace, NW8, in the City of Westminster area. Mr Gideon (with tenant Larry) lives at number 3. Amelia Bird lives at 4, Hazell Lovett is at 5, and the Ropers with Robin, Chrissie and Jo are at number 6.
