Kate Winslet reportedly held her breath for seven minutes and 15 seconds on set for Avatar: The Way of Water. Some of the movie’s scenes were filmed underwater.
It’s a remarkable feat; anyone (including professional freedivers) would acknowledge that a breath hold over seven minutes is extremely difficult. Most professional freedivers must train for years before reaching a number like that — many never achieve it. Winslet apparently trained only for a few weeks.
