Cast members who have played minor roles in the televised Doctor Who universe who have gone on to play major ones (and vice versa). No other show has as dedicated or rich a history of reusing talent, and it really wouldn’t be the same without it.
This doesn’t even include people like Lohn Levene, whose face was hidden when he played Cybermen and Yetis before taking on the recurring role of Sergeant Benton; or Naoko Mori, whose earlier appearance in Doctor Who was retconned into being Toshiko Sato, the same character she plays in Torchwood; or the dozens upon dozens of people who have played aliens and multiple one-off characters in a variety of stories throughout the show’s history, in both the classic and new eras (sometimes even both).
That would be nigh on impossible.
