Epic new Dunkirk trailer shows fierce fighting scenes

The latest trailer for Christopher Nolan's wartime flick Dunkirk has been released - and it shows in dramatic detail the fear and horror of WWII.

Dunkirk is set in the midst of World War II and is based on the event known as Operation Dynamo, which was the mass-evacuation of Allied soldiers from France - a moment described as a "miracle of deliverance" by Winston Churchill.

The trailer shows Allied forces under attack by German planes as they wait helplessly on the beach, while the British nation attempts to come to their rescue with a flotilla of civilian boats.

The film boasts an all-star cast including the likes of Kenneth Branagh, Cillian Murphy, Tom Hardy and One Direction crooner Harry Styles, who features in a breakout role.
