Pennant Roberts (15 December 1940 - 22 June 2010) 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 DW: Shada, footage from which was later repurposed for inclusion in the twentieth anniversary episode The Five Doctors.
He was the only person to direct Doctor Who serials in both the 1970s and the 1980s.
