Classic speech from the Earth Summit in Rio (1992).
A great use of film and frame by frame animation.
with a very powerful voice over.
Pure animation with no speech at all.
2D and 3D animation and photographs with voice over.
Frame by frame animation on a white board.
Amateur camcorder footage - great message but poor production.
A presentation with a voice over - so easy.
Simple graphics, simple message, big impact.
Professional mix of film and interviews to examine the future.
