We made those shows back 1999 to mark what was then the first century of cinema and in the final programme (which was a kind of 'state of the union' summary of where the movies had got to on the eve of the new millennium) David Puttnam expressed the hope that if we'd done a good enough job, the BBC might invite us back to present the sequel.
Well, tonight you can hear that sequel as David and I cogitate on what's been going on in the cinema over the past decade: the digital revolution, the decline of star-name box-office champs and the rise of the franchise; the continuing success of independent filmmaking (with input from Robert Redford at Sundance) and the ongoing importance of Oscars and BAFTAS - despite Sunday's marathon where Jonathan Woss delivered a tediously unfunny script, where most of the presenters had to peer helplessly into the back of the auditorium of the Royal Opera House in a attempt to read the auto-cue and Vanessa Redgrave sadly made a speech that was neither amusing nor politically bonkers.
We'll be talking about Pixar and Potter (Harry that is, with a visit to the studio where they're busy working on the seventh film in the series); about why Twitter is the new word-of-mouth that can decide, in just one day, the fate of the movie and whether - this time - 3D really is here to stay!
You can hear David Puttnam's Century of Cinema - 'Reel 6: The Sequel' - on BBC Radio 2 at 10:30 pm, and, if you miss the transmission this evening, it can be heard again for the next seven days via the BBC iPlayer.
And, until the transmission of tonight's episode, you've still a few hours left to catch 'Reel 5: The British Are Coming', looking at the British film industry.
