The Mind of Evil was a Third Doctor story that brought a radical change in the way United Nations Intelligence Taskforce was portrayed. Instead of being a primarily investigative body interested in alien or unexplained phenomena, here UNIT was mostly seen as a simple security force, guaranteeing the safety of international diplomats. In other words, the "United Nations" portion of their acronym was stressed over the "Intelligence Taskforce" bit — as would later happen in such stories as Day of the Daleks and The Time Warrior. Meanwhile, the main plot about the mind-control device was something writer Don Houghton intentionally included as an homage to A Clockwork Orange. Evil went badly over budget, thanks in no small part to one of Doctor Who's rare usages of a real helicopter in the concluding episode. An unimpressed Barry Letts therefore withdrew director Timothy Combe from his informal "director's rota", and Combe never worked on the programme again.
