The guest cast starts getting whittled down pretty massively by this point. The Silurians’ plague claimed Major Baker in the previous episode. This time, both Geoffrey Palmer’s and Peter Miles’ characters die from it. I enjoyed the location filming, which was done in late 1969 around Marylebone train station in London, and sees lots of commuters succumbing to the virus after Palmer’s character senselessly takes a train back to his ministry office despite what he’d learned in the previous episode.
Our son was very attentive this morning, and that’s a little surprising considering how very measured and slow this episode is. The scenes of the Doctor and Liz working in the lab are quite long; you can’t imagine modern television spending so much time on quiet scenes of characters mixing drugs and testing them on blood samples under a microscope. They really work; Jon Pertwee and Caroline John really sold just how heavy and critical their work is.
Still, a little levity was needed after such a dark half-hour. Having received a fright when the Silurians attack the Doctor to stop the spread of the cure he’s found, he’s kicking back in front of the TV with something much lighter now: Disney’s cartoon Robin Hood.
