Vietnam War, with added dinosaurs: Jeremy Piven on the mad mix of his latest film 

The former Entourage star had a ball making Primitive War, he tells Esther McCarthy

A scene from Primitive War, starring Jeremy Piven as a soldier whose tour in the Vietnam War takes an unexpected turn. 

Playing a powerful agent in Hollywood in the award-winning Entourage has been one of his most-successful career moments. But actor Jeremy Piven has always loved to mix it up - and when the opportunity came to make a dinosaur film set during the Vietnam War in remote Australia, he jumped at the opportunity.

The result is Primitive War, a film that blends the dramatic horrors of conflict with the tension of a large-scale creature feature. Set in Vietnam in 1968, a unit named Vulture Squad is sent to an isolated jungle to uncover the fate of a missing Green Beret platoon, only to discover that they’re not alone, and fierce dinosaurs walk among them.
