Behind the scenes
There was some initial discussion about the possibility of Strax wearing a kilt in the TV episode The Name of the Doctor, as Strax is in Glasgow at the start of that episode. The character would have worn the kilt throughout the instalment. However, the garment would have required Strax actor Dan Starkey to wear prosthetic legs and there was insufficient time for those to be crafted. Starkey remarked about the kilt, "It would have been hell to wear. But it would have been great!" Vastra actress Neve McIntosh agreed that having Strax wear a kilt throughout the episode would have been "fantastic." (DWM 475, p. 18)
