The Mind of Evil - Episode 4

Good location work in this episode, with the capture of the Thunderbolt missile by Mailer's fellow prison henchmen. Again we see the Third Doctor leg-crook. But wait, he's lying down and both his legs are straight! Hmm. Perhaps when his head is somewhat elevated he can stretch it down. Interesting to see Yates and Benton get beaten. The Brigadier looks just too much like Peter Sellers as Group Captain Lionel Mandrake from "Dr. Strangelove" in this episode. And we get another silly "Doctor making goofy terrified faces at threatening menace" cliffhanger, this time with Jo by his side.
