Gerry Anderson was informed that New Captain Scarlet would be aired in a Saturday evening slot, same as the BBC did with the new series of Doctor Who (2005), which had also done very well in that same time slot. However at the last moment ITV, who had invested a large amount of money into New Captain Scarlet, went to Gerry and his production company and asked them to replace the series theme music with an updated version of the original Captain Scarlet and the Mysterons (1967) theme. The costs involved would have been enormous and would have been met by the production company rather than ITV, so Gerry refused, knowing that there would be consequences and so ITV buried New Captain Scarlet in a Saturday Morning slot within the Ministry of Mayhem show, splitting each episode in two and providing very little publicity.
Both Destiny Angel and Captain Scarlet looked slightly different after the first two episodes, with new hairstyles and slightly varied features. This is because the production company changed after the pilot episodes in order to shoot the rest of the series.
Certain characters had their nationalities changed from the portrayals of their characters in the 1960s series. Captain Scarlet became a British/American national as opposed to his tradition purely English roots, while Destiny Angel dropped her obvious French background to become an English girl (with British/American nationality) in this newer version.
In "Mercury Falling" Captain Black is looking up names of people on a computer, 3 files come up on screen with pictures the people in the pictures are of Ron Thornton the CGI Producer, Harvey Randhawa the CGI Lighting and Josh Simmonds the CGI director for Blue Team.
Captain Scarlet and the Mysterons (1967) was made using "supermarination" ('Gerry Anderson(I)'s name for the technique used to make the puppets mouths move in time to pre-recorded dialogue), this new series has been made using "hypermarination" (Anderson's name for animating the characters through motion capture CGI technology).
The supposed real names of the agents were Paul Metcalf for Captain Scarlet, Adam Svenson for Captain Blue, Simone Girradaux for Destiny Angel and Charles Grey for Colonel White. Lt Green was also known as Serena Lewis, Ochre was Elaine McGee, Harmony was Rebecca Drake, whilst Captain Black's real name was Conrad Lefkon.
