Doctor Who (series 11) [SEP] Filming
Pre-production for the eleventh series began in late October 2017. Filming officially began on 31 October 2017, and concluded on 3 August 2018. Jamie Childs directed the first and ninth episode of the series in the opening production block, having directed Whittaker's introduction video as the Thirteenth Doctor. Sallie Aprahamian directed the third filming block, consisting of two episodes. The eleventh series was shot using Cooke and Angénieux anamorphic lenses for the first time in the series' history, a creative decision made in order to make the show look more cinematic. In November 2017, the production team visited parts of Sheffield, where they filmed a majority of "The Woman Who Fell To Earth".
