Every script carried an explanatory outline by The Saint's creator Leslie Charteris for the cast and crew: "I have been trying to make a picture of a man. Changing, yes. Developing, I hope. he is a roaring adventurer who loves a fight ..... a dashing dare-devil, imperturbable, debonair, preposterously handsome, a pirate or a philanthropist as the occasion demands. He lives for the pursuit of excitement .... for the one triumphant moment that is his alone. Fantastic? Improbable? ..... perhaps. It doesn't matter so long as you feel that you would recognize him if you met him tomorrow."

The few bars of music heard at the start of every episode when the halo appears above Simon's head is from the original The Saint theme used for the radio and film series in the 1940s, and also in ITC's 1960s television series. It is credited to The Saint Creator Leslie Charteris.
Templar's wardrobe came courtesy of noted fashion designer Francesco Smalto, from London's celebrated Jermyn Street.
Early publicity for the series gives it the working title "Son of the Saint".
