Always have a soft spot for Genesis. I remember watching the repeat showing in the 1980s and being stunned when my Dad told me that "Ronson" was his art teacher at high school.

Spearhead from Space was one of the first stories I bought on VHS and I watched it so many times, so that's a definite favourite too. Oh, and Ark in Space.

Pyramids of Mars. The City of Death. The Key to Time. Trial of a Timelord. Anytime Jon Pertwee, Roger Delgado and Katy Manning were on screen it was magical.

Too hard to narrow down the entirety of the classic series, so here's one story for each classic Doctor:

• The Tenth Planet
• The Mind Robber
• Carnival of Monsters
• State of Decay
• Kinda
• The Two Doctors
• The Happiness Patrol
