Phelps and Paris introduce the antagonistic act they would use often this season, pitted against each other to manipulate the target.
The inflatable dummy of Torin Thatcher used in the medical tent was incredibly realistic. Lee Meriwether recalled the cast and crew broke for lunch and forgot about Thatcher, as he had fallen asleep and had been mistaken for the dummy.
Lee Meriwether, passed over in favor of Dina Merrill in The Controllers: Part 1 (1969) & The Controllers: Part 2 (1969), was brought on board as Tracey for the first of her four operative roles. Her part was rather minor, as she mostly alerted the team in the bunker to any actions that would expose the ploy.
Selected by Phelps during the dossier scene, the redoubtable Hartford Repertory Company makes its second appearance.
Willie is not involved in the physical aspects of the mission. He appears as the proper and staid Herr Huffman, some sort of liaison for the funds in the Swiss account of General Gollan.
