Dame Helen Mirren and Olivia Colman have landed new roles as endangered sea turtles in a film aimed at raising awareness of the crisis facing the world’s oceans. The stars, both famous for playing the Queen, voice the parts for Turtle Journey, made by Wallace And Gromit creators Aardman in collaboration with Greenpeace. The animated short depicts a family of turtles facing oil drilling, plastic pollution and industrial fishing as they try to get home. Dame Helen, who plays the family’s grandmother, expressed sadness that her generation would leave future ones a damaged planet “which has already lost so much of the biodiversity that makes it special”. “During my lifetime, I’ve seen nature being destroyed on an unimaginable scale by human activity,” Dame Helen said. “However, we have a chance to do something now and leave a legacy of properly protected oceans to all the people who come after us. “We can’t bring back what we’ve already lost, but we can protect what we still have. I hope this film will help to make more people realise the ocean is worth protecting, and inspires us to act before it’s too late.” Greenpeace has released the short film as part of its push for a new Global Ocean Treaty at the UN summit and the publication of its report Turtles Under Threat.
