Director (Doctor Who? 180)
From Tardis Wiki, the free Doctor Who reference
In Earth-33⅓, a director for the BBC was in charge of the scene that depicted the First Doctor's regeneration into the Second Doctor. Rehearsals took place in November 1966. At one point, he asked for another take which, to his horror, resulted in the Third Doctor being called to set. (COMIC: Doctor Who? 180 [+]Loading...["Doctor Who? (DWM 180 comic story)"])
