Presented by Dominic Sandbrook, episode four was all about time travel, and naturally encompassed Doctor Who.
Interviewed were lead writer Steven Moffat, actors David Tennant and Karen Gillan as well as Neil Gaiman who talked in gerbil terms about sic-fi rather than specifically about Doctor Who.
The thing that really caught my eye though was seeing the Tom Baker coat from the classic series Doctor costumes display.
This is a coat I made for the exhibition, and it was on display during 2012 and 2013.
