Darth Vader first appeared in Star Wars in 1977, played in costume by David Prowse and voiced by James Earl Jones. Sound designer Ben Burtt created the breathing by recording himself breathing through a scuba diving regulator, giving the character a mechanical life-support sound that matched his mask. The effect became one of the most recognisable sounds in cinema and moved easily into trailers, parodies, toys and internet edits. Decades later creators still drop it in whenever a scene needs instant villain energy without any explanation.
