To The Limit presents, for the first time ever in the giant screen format, staggeringly beautiful scenes from inside the body that reveal its miraculous ability to adapt to the demands of intense physical action. Special camera equipment developed just for this film takes you on a “miniature helicopter ride” through the heart, arteries, and even down to the microscopic level to witness the actual oxygen exchange of red blood cells in tiny air sacs of the lungs. Photographed in the Soviet Union, England, and the United States.

Length: 38:00
