Principal photography commenced in April 1969 with production based at MGM-British Studios in Borehamwood. Seventeen episodes were filmed at these studios before they closed at the end of 1969. Production resumed at Pinewood Studios when studio space became available in June 1970, leading to an unusual seventeen-month long production before the final nine episodes were completed. The delay in production saw both George Sewell (who played Alec Freeman) and Gabrielle Drake (Lt. Gay Ellis) both drop from the cast as they were no longer available.
