Billie Piper
After the completion of the very successful first series of the revamped Doctor Who, the British media regularly released conflicting reports about how long Piper would be staying with the programme. In March 2006, she claimed that she would continue on Doctor Who into its third season in 2007. On 10 May 2006, however, she was reported to be considering quitting the series, although she did express an interest in playing a female version of the Doctor in the future (possibly related to a proposed Doctor Who spin-off series about Rose which was later dropped). On 15 June 2006, the BBC announced that she was to depart in the final episode of the second series, "Doomsday". Piper's decision to leave had been taken a year previously, but remained a secret until news of her departure became public.
