An unofficial film trailer has been released ahead of Pope Francis’s upcoming encyclical on the environment which will be issued on Thursday. The trailer, which has already received nearly 60,000 views on YouTube, was created by Brazilian climate action group Observatório do Clima and shows the pontiff taking part in the fight against climate change. In the trailer, a Pope Francis look-a-like engages in Rocky-style boxing training and confronts an eye-patching wearing Bond villain. The much-anticipated encyclical, Laudato Si, will be published on Thursday. A Catholic, an Orthodox Christian and an atheist will present the encyclical in the synod hall at the Vatican. The Pope told an audience of priests in Rome that the line-up would reflect the fact that “we need unity to protect creation”.
