The Lost Stories were originally written as TV scripts before the season for which they were written was scrapped in favor of Trial of a Time Lord (what were they thinking?!?).
I have all of these titles from waaaay back. The first series of Dalek Empire was released circa 2001; the most recent release, the Lost Stories, were from ’09. So nothing terribly new here. All of Tennant’s voice work from Dalek Empire predates his becoming the Doctor and fighting Daleks on TV by at least a year.
