This year, the long-running SF series Doctor Who is sixty years old - so Colin and Phil turn back the clock and watch the very first episode of the series, from 1963: "An Unearthly Child".

Phil's first proper Doctor was the third one, played by Jon Pertwee, although he has vague recollections of the second doctor (Patrick Troughton). On the other hand, like many Americans, Colin first knew of the show from the Tom Baker years.

What will they make of the gruff, original Doctor portrayed by William Hartnell?

We also have our usual skip through past, present and future science fiction.
