We kicked off proceedings with William Hartnell classic 'The Aztecs', while Jon Pertwee's 'The Daemons' filled the number 9 spot. This week, we're heading into the Patrick Troughton era for a stone cold classic once thought lost forever...
8. THE TOMB OF THE CYBERMEN (1967) - Four episodes - written by Kit Pedler and Gerry Davis
Series 5 of Doctor Who is often referred to as one of the show's all-time great runs, but it would have been so easy for Patrick Troughton's first full series as the Doctor to get off to a rocky start. While 'The Tomb of the Cybermen' saw the return of fan favourites the Cybermen, it also marked the debut of a new producer - Peter Bryant - and new (one-time) script editor - Victor Pemberton - for the show.
There were no early stumbles here though. Bryant's tenure on Doctor Who kicked off with a real gem - a phenomenal four-parter with the feel of a pulpy '50s sci-fi flick, and that's absolutely not intended as a criticism!
If you're ever looking to convince a young 'un, or for that matter an adult sceptic, that classic Doctor Who is worth a punt, stick on 'The Tomb of the Cybermen' - the 1967 serial certainly did the trick for a certain Matt Smith in 2011...
"It's so creepy," the 11th Doctor actor enthused at the time. "What I think is wonderful about Troughton is he's weird and peculiar but he never asks you to find him weird and peculiar. He was a great actor. And I think the Cybermen are as scary as they've ever been in that one story."
He's not wrong. Doctor Who's second most popular monsters have never been more creepy than here - with their electronic, buzzing voices and, in one of the show's most celebrated scenes, their slow, deliberate crawl from their icy tombs, scored by M Slavin's absolutely wonderful 'Space Adventures (Parts 1-3)'.
Said sequence is but one of many iconic Who moments contained within 'The Tomb of the Cybermen'. There's also one of the show's greatest ever Doctor-companion scenes, as Troughton's Time Lord consoles the gentle Victoria (Deborah Watling) over the recent loss of her father and briefly recalls his own family. It's utterly magical stuff.
So much of what makes 'Tomb' work is down to Troughton, an intensely charismatic leading man who - despite finding himself surrounded by a superb roster of character actors - is never in any danger of fading into the background.
Here, the second Doctor is by turns commanding, menacing, warm and laugh-out-loud funny - and this adventure sees him surrounded by a similarly colourful supporting cast. George Pastell and Shirley Cooklin are wonderful as chief villains Klieg and Kaftan - cunning and camp, like Bond villains in space - while Aubrey Richards and Cyril Shaps also deliver performances of note as the dignified Professor Parry and frantic Viner.
'The Tomb of the Cybermen' was for the longest time thought lost - tragically junked like so many of Doctor Who's '60s episodes - before all four episodes were rediscovered in Hong Kong in the early '90s. Now fans have back in their possessions one of the finest examples of the archetypal Who story.
A base under siege, classic monsters, vibrant villains, real emotion, real scares and terrific humour - much of it courtesy of the Doctor and Scots companion Jamie, with the Troughton / Frazer Hines pairing at its absolute peak.
In many ways, 'The Tomb of the Cybermen' set the standard. It's the story that every other Doctor Who adventure wants to be.
