Michael Ferguson was one of the few directors to direct stories of the First, Second and Third Doctors. He was also an uncredited assistant floor manager during the Daleks' debut serial (with Jeremy Hare). Part of his duties on this serial required him doing a bit of performing. Being also a member of Equity (having previously worked as an actor), he nominally played the first Dalek, operating the Dalek sucker arm that threatened Barbara Wright at the end of the episode "The Dead Planet".
