 Sylvester McCoy (qv) was the first actor to play two incarnations  of The Doctor. In 1987, Colin Baker (I) (qv) refused to film a  regeneration sequence after being dropped from the lead role, so  McCoy donned a blond wig and portrayed an unconscious 6th Doctor  just prior to his transformation into Doctor #7. The second actor to  play two different versions of the Doctor was  Richard E. Grant (qv), having played The "Quite Handsome" 10th  Doctor in the BBC Comic Relief charity spoof  _Comic Relief: Doctor Who and the Curse of Fatal Death (1999) (V)_ (qv).  He then went on to voice the 9th Doctor in the BBC web animation  _"Doctor Who: Scream of the Shalka" (2003) (mini)_ (qv).
