Carter has been cast as Jesus in several productions of Jesus Christ Superstar.[2] In 1996, 16 years after the closure of the original production of Jesus Christ Superstar, the Really Useful Theatre Company revived the show in the West End, in which Carter was originally cast as Simon Zealotes before replacing Steve Balsamo as Jesus. In 1998, Really Useful mounted a touring production in the UK which did not include Carter in any of the leading roles.
Carter has been the Leader of the UK branch of the Raëlian Movement since 2002.[4][5] According to Raëlian doctrine, humans were created by extraterrestrials. The organisation's head, Raël (former auto racer Claude Vorilhon), founded the Movement in 1973 at the request of the President of the extraterrestrials′ governing body and declared that the world should be governed in the form of a "money-less society, governed by a World College of Geniuses".[6]
In 2002, in the week following the claim by Clonaid (which has ties to Raëlism) to have cloned a human, Carter told the press "the evidence would be supplied in the next few days".[7] In February 2003, it was announced that Carter would participate in a panel debate on the ethics of human cloning before an audience of Oxford University students.[8][9]
