a "possible miscalculation" on the part of the series creators. In support of his argument, he points to a scene in the episode "Attack on Cloudbase" in which Lieutenant Green scoffs, "Anyone can be brave if they're indestructible." Commenting on the 2000s remake, Andrew Billen noted that the new version of the character was referred to as being "virtually indestructible", arguing that the use of a qualifier made the premise more exciting and "fixed every child's main objection" to the original series. John Peel believes Captain Scarlet's self-healing power to be a major weakness of the original series. He also suggests that the character served as a poor role model to the "impressionable children" who made up most of the audience: "Parents didn't like their children watching a show that appeared to be encouraging them to hero-worship someone who was indestructible." He cites Batman as another 1960s TV series whose young viewers "sometimes tried to copy their heroes, often with nasty or lethal results." Peel believes that the incitement to act dangerously is sustained by the series's lyrical closing theme music, which includes the lines "They crash him, and his body may burn" and "They smash him, but they know he'll return ... to live again." These lyrics led production company Century 21 to make an alternative set of opening titles featuring a disclaimer, in the form of a voice-over by Donald Gray in character as Colonel White, warning: "Captain Scarlet is indestructible. You are NOT. Remember this. Do not try to imitate him!" Religious allegory Captain Scarlet has also been interpreted as part of a supposed religious allegory in the series. Various sources have commented on the idea that the character's self-healing ability makes him an analogue of the resurrected Jesus. Actor Cy Grant, who voiced the original Lieutenant Green, made several observations on the series's alleged religious symbolism. He believed that Colonel White and Captain Scarlet symbolised God and the Son of God, while Captain Scarlet's nemesis, Captain Black, represented the Devil. La Rivière and others note that like the ascended Christ, Captain Scarlet lives in the sky with Angels – on Spectrum's airborne headquarters Cloudbase, which is defended by a fighter squadron codenamed "the Angels". But Gerry Anderson always denied that any of this symbolism was intentional. Adaptation In the BBC Past Doctor Adventures series – a series of novels based on Doctor Who, featuring the first
