We meant to watch part six of this serial last night, but we got home too late. So we doubled up again, and really enjoyed this story. I love how the tension in part six just keeps ramping up, even with a plot that doesn’t fill its running time, necessitating a bit where characters run back to a previous location to try one more time to restart the power. It works because the actors really convey their desperation, and Nicholas Courtney’s Brigade-Leader falling apart from the stress is a great, great moment.
After that, and the fabulous cliffhanger of the sea of lava coming to engulf the hut and kill all the parallel universe doubles, the final part can’t help but feel like an anticlimax to older viewers who are familiar with the rules of drama. But it’s paced so darn well for the younger members of the audience! There’s even a bit where the grown-ups are bound to ask whether it’s absolutely necessary for Jon Pertwee to climb up yet another bit of scaffolding in this refinery, and the children will answer that of course it is; he needs to fight another green monster up there. Our son had a ball with both parts. If he uses a make-believe “fire extinguisher” to defeat my playground alter ego of “Daddy Monster,” I wouldn’t be at all surprised.
“Inferno” would be the last Doctor Who serial directed by Douglas Camfield for five years, damnably, and also the last appearance for Caroline John and her character, Liz Shaw. Barry Letts and Terrance Dicks had concluded that the character didn’t really work (they were mistaken), but the actress had already decided to leave. In 1982, she worked with Barry Letts again in the BBC’s four-part adaptation of The Hound of the Baskervilles. She was a regular face in guest star roles throughout the eighties, and reprised her role as Liz Shaw in the four direct-to-video P.R.O.B.E. movies from 1994-96. In a 2010 episode of The Sarah Jane Adventures, Liz is said to be working on UNIT’s Moonbase (really!), but the actress did not appear onscreen. She passed away in 2012 at the age of 71.
