King of Beasts: The Story of Lion Trophy Hunting follows an American hunter's "relentless pursuit" of his 14th lion trophy in Africa as activists around the world seek to secure the big cat's survival.

Co-directors Harel and Almagor have completed filming and they now need $50,000 (GBP35,000) to help them wrap up post-production and so they have set up an IndieGogo campaign in a bid to hit their goal.

The filmmakers began the project in the summer of 2011 and spent four years making the documentary.

Harel tells WENN, "King of Beasts tells an unvarnished story of an inconvenient reality, laying out the powerful facts for anyone striving to revolutionise the politics of our natural treasures on a global scale. Our time filming in the wilderness of Namibia and Tanzania revealed a complex economy of conflicts, territory, food, and money."

"It's not romantic," Almagor adds. "I started this project with the intention of saving African lions. I've met trophy hunters, scientists, activists and even politicians. The relationship between man and nature in Africa today is far more complex and nuanced than I anticipated, but I hope that our film serves as an alarm call, and a platform for dialogue between all the different parties involved, on the way to change and conserve our wildlife for future generations."

The film is extremely topical as it comes in the wake of the death of Zimbabwe's beloved Cecil the Lion, who was killed by an American big game hunter last year (15).
