Outdoor filming for the second episode—a first for the show—took place on 15 June 1964. Led by cameraman Peter Hamilton, a crew shot inserts of the Doctor, played by Brian Proudfoot in William Hartnell's absence, walking to Paris; Denham, Buckinghamshire was selected as the location by Combe due to the "French-looking" lanes, particularly the avenues lined with tall trees. Inserts of Russell for the second and third episodes were recorded at Ealing Studios Stage 3A from 16–17 June, in preparation for Russell's holiday. Further inserts were recorded on 18 June at Ealing Studios Stage 3.
