A Clockwork Orange research

• Director Stanley Kubrick was busy developing a Napoleon Bonaparte-related project, but was persuaded to pursue A Clockwork Orange after his wife gave him the novel after having read it. Kubrick immediately wanted to produce a film adaptation. 
• Author Anthony Burgess had mixed feelings about the film, blaming the US publishers omission of a redemptive final chapter he had written for the film's altered ending. Although publicly he was enthusiastic. Their relationship hit a stumbling block when Burgess was left by Kubrick to defend the film himself from Christian organisations over 'glorified violence'.
