While the Doctor was exiled to Earth, he had to learn to survive while stuck in one place and time. At first he was quite literally stuck with U.N.I.T., led by Brigadier Alistair Gordon Lethbridge-Stewart, who had confiscated the Doctor’s TARDIS. Eventually the Doctor came to rely on a small group of people within U.N.I.T., and many have referred to them as his family. Along with the Brigadier, they included Captain Mike Yates, Sergeant Benton, and his assistant and companion, Jo Grant.
Seeing Richard Franklin, John Levene, and Katy Manning together, you get the sense that there definitely was a family like group on set during their era. The way they joke and tease each other was just so much fun to watch. They also told many stories of cast members who are no longer with us – Jon Pertwee, Nicholas Courtney, and Roger Delgado. I was very excited to see this trio, and I was not disappointed!
