It was a big night at the Oscars on Sunday for the blockbuster “Oppenheimer” that won the most awards. GBH with partners Associated Press also won an Oscar for best documentary for their film of a Ukrainian city under siege by the Russian military called “20 Days in Mariupol.” Sound plays a big role in crafting any good film and one that was nominated in the best sound design category was “Society Of The Snow.”The World’s Gerry Hadden brought us this story about that film earlier this year.
