All you need to know about this before viewing the trailer below is that Werner Herzog has made a documentary film in 3D about the Chauvet Caves, which contain the earliest known cave paintings in existence.

Knowing this, and knowing that the extreme delicacy of the caves meant that Herzog’s ability to capture footage from the cave’s interior was severely limited, the trailer below shows off some astonishing scenes, and whatever you think of 3D in cinema this is sure to be a unique experience.

It debuted at Toronto last year and garnered some amazing reviews, which are emblazoned over the trailer, which you can view below.
