(Talking about the audience of "The Sarah Jane Adventures" prior to the second series being aired and how the age of the audience influence the show)
Russell: The one thing I demanded is that the threat would always be real rather than comic, though we make it a lot lighter and with a lot less fear. On Doctor Who we consider the eight-year-olds or the 10-year-olds, but with this you seriously have to think of six-year-olds. It doesn't sound like there is much difference between 6 and 8, but they are actually a vastly different creature. Part of you also has to remember that the six-year-olds watching the series last year are seven-year-olds now, and they are into it, they get the mythology and want to see things dealt with in detail. So the scripts for this second series are a little more complex.
