Pennant Roberts
From Tardis Wiki, the free Doctor Who reference
Pennant Roberts directed several Doctor Who stories during the Tom Baker era and one each featuring Peter Davison and Colin Baker. His work included the uncompleted story Shada, footage from which was later repurposed for inclusion in the twentieth anniversary episode The Five Doctors.
He is the only person to direct Doctor Who serials in both the 1970s and the 1980s.
