The Taken star has provided the voice of the Almighty for a new advert, directed by Curtis, which is to be shown in cinemas across the world to promote the United Nations' goals to fight issues such as poverty and climate change.

The Project Everyone scheme has been masterminded by Curtis in a bid to share the U.N.'s targets with citizens all over the globe.

Speaking during the Cannes Lions International Festival of Creativity in France, Curtis explains, "We want to try to make sure everyone on the planet knows about this to-do list for the planet... (It will be) an ad that everyone can understand... a shared common experience... I'm hoping that people will watch, laugh, share, act."

Curtis' Project Everyone drive has been backed by other stars including Freida Pinto and Chiwetel Ejiofor.
