Described as the "Inconvenient Truth of the Oceans", the End of the Line predicts that if overfishing continues, there will be no more seafood by 2048 - threatening many areas of the world with starvation.

In the new film Daily Telegraph journalist Charles Clover confronts the politicians who have failed to stop overfishing and the celebrity restaurateurs who continue to serve endangered species like bluefin tuna.

Ted Danson, the Cheers actor and founder of Oceana, the largest international group focused solely on ocean conservation, predicted the film will turn ordinary people into activists against non-sustainably sourced fish.

"It will infuriate you because this does not have to happen. This will make you an activist," he said.

"There is still time to change our ways so if you want to be able to answer your kids and say this is what I did when I found out we are fishing out our oceans, this is how I stopped it, you should watch this film."

The film, selected for the 2009 Sundance Film Festival, features indigenous fishermen, top scientists and campaigners all around the world, from the coasts of Senegal to the Tokyo fish market and Senegal.

Mr. Danson urged people to find out more about the threat to the world's oceans.

"This is not the environmental alarmist. We, conceivably could fish out our oceans in the next 40 or 50 years," he said. "This is science."

The End of the Line will be previewed at cinemas across the UK World Ocean Day on the 8th June.
