How sound designers created Godzilla's roar

This 45-minute video is a fun behind-the-scenes look at how sound designers created Godzilla's blood-curdling roars, and other terrible noises emitted by the monsters in Gareth Edwards's movie. They ran their fingers over a squeaky red balloon, raked a plastic comb's teeth over a tire's tread, rubbed a sneaker sole against a drumhead, opened a creaky ironing board, and manipulated other ordinary objects, and then ran the recordings through software to create the ghastly sound effects.
