Howling:Ginger Doctor?

Does anyone know where the 10th and 11th Doctor's desire to be ginger comes from? Did Russel T Davis always want to see a ginger Doctor or is there more too it?

Second question: Does anyone want a ginger Doctor? Since we now know the Doctor copies his faces from people he met(subconsciously), maybe Tony Curran would be a good choice. Assuming he's not still busy with Defiance at the end of Capaldi's run. 71.127.243.148talk to me 02:30, August 26, 2014 (UTC)
