Adam Strange drove around London in an Austin FX3 taxi cab (reg: TYK 822), because he could park anywhere for long periods of time and go unnoticed in any neighbourhood.
The series was a huge success in both England and in America, and a second season was planned. However, the production team wanted to move to America to film the second season, and neither Anthony Quayle nor Anneke Wills wanted to leave the country. Thus, a second season was never produced.
The show was made by American producers and an American scripted despite being made in England. As a result, from the first time Anthony Quayle and Anneke Wills got a script, they started re-working the lines to make their dialogue sound more genuinely English, with the full blessing of director Charles Crichton.
Despite the producers having a deal with a store in Carnaby Street for Anneke Wills' wardrobe, she mostly wore her own clothes, some of which she made herself, because they were more fashionable for the time. She even had a sewing machine in her dressing room in case she needed to come up with something quickly.
