Simon Templar ( Sir Roger Moore) is the Saint a millionaire playboy who is the scourge of the police world wide because taking matters into his own hands to help those in need or danger . Templar is a fantastic creation who is handsome, smart and caring but also has a darkside and believes in a tooth for tooth and an eye for an eye and is not above killing those who he thinks deserve it. A great show with some great co stars and story's that still stand up today but of course the real star here is Moore's performance.
The seaview is the most powerful craft on or under the seven seas. The main crew members are captain Lee Crane ( David Hedison) and Adm. Harriman Nelson designer of the seaview who every week along with the rest of the intrepid crew battle either some type of creature or Cold War / Bond type situation. The first season is black and white but the following three seasons are colour. By the second season we saw less and less " serious " story's and more creature of the week episodes.
