Karen Gillan was a big hit with Doctor Who fans in the first two series. The sci-fi drama is down 1.2 million viewers from last series, but I venture it would have seen even worse viewing figures were it not for the new redhead in very short skirts.
In the past there have been some very cute assistants too, one who does spring to mind is right here.
Nicola Bryant played Perpugilliam Brown, or Perri and was notable for a couple of things (see image below). OK there was more to her than that. She fought not only the Doctor’s enemies but the constantly diminishing budgets at the end of Colin Baker’s tenure as The Doctor.
Her (literally) bouncy nature seemed to make up for so much that was lacking in the later story lines, like say money and commitment form the BBC. Until, after her demise the whole series descended into farce with the advent of Bonnie Langford and Sylvester McCoy.
There are times when you need a bouncy young assistant running towards camera to distract viewers from the cardboard sets and Nicola filled that role perfectly.
