He has offended Muslims worldwide and al-Qaida wants him dead, but the Swedish artist who portrayed the Prophet Muhammad as a dog said Monday he has no regrets. Lars Vilks, 61, told The Associated Press he might use the uproar over his drawings as the subject of a musical, with prominent roles depicting Iran’s president, Sweden’s prime minister and al-Qaida terrorists. “The Muhammad cartoon project must be made into an art work,” said Vilks, breaking away for an interview during a business seminar in Klippan, a small town in southern Sweden. “A musical comes to mind … I think it would help the debate.” The eccentric sculptor said previously that the cartoons weren’t meant to insult Islam but rather to test the boundaries of artistic freedom.
