In 2019, two multimedia artists, Francesca Panetta and Halsey Burgund, set about to pursue a provocative idea. Deepfake video and audio had been advancing in parallel but had yet to be integrated into a complete experience. Could they do it in a way that demonstrated the technology’s full potential while educating people about how it could be abused?
To bring the experiment to life, they chose an equally provocative subject: they would create an alternative history of the 1969 Apollo moon landing. Before the launch, US president Richard Nixon’s speechwriters had prepared two versions of his national address—one designated “In Event of Moon Disaster,” in case things didn’t go as planned. The real Nixon, fortunately, never had to deliver it. But a deepfake Nixon could.
So Panetta, the creative director at MIT’s Center for Virtuality, and Burgund, a fellow at the MIT Open Documentary Lab, partnered up with two AI companies. Canny AI would handle the deepfake video, and Respeecher would prepare the deepfake audio. With all the technical components in place, they just needed one last thing: an actor who would supply the performance.
“We needed to find somebody who was willing to do this, because it’s a little bit of a weird ask,” Burgund says. “Somebody who was more flexible in their thinking about what an actor is and does.”
While deepfakes have now been around for a number of years, deepfake casting and acting are relatively new. Early deepfake technologies weren’t very good, used primarily in dark corners of the internet to swap celebrities into porn videos without their consent. But as deepfakes have grown increasingly realistic, more and more artists and filmmakers have begun using them in broadcast-quality productions and TV ads. This means hiring real actors for one aspect of the performance or another. Some jobs require an actor to provide “base” footage; others need a voice.
For actors, it opens up exciting creative and professional possibilities. But it also raises a host of ethical questions. “This is so new that there’s no real process or anything like that,” Burgund says. “I mean, we were just sort of making things up and flailing about.”
“Want to become Nixon?”
The first thing Panetta and Burgund did was ask both companies what kind of actor they needed to make the deepfakes work. “It was interesting not only what were the important criteria but also what weren’t,” Burgund says.
For the visuals, Canny AI specializes in video dialogue replacement, which uses an actor’s mouth movements to manipulate someone else’s mouth in existing footage. The actor, in other words, serves as a puppeteer, never to be seen in the final product. The person’s appearance, gender, age, and ethnicity don’t really matter.
But for the audio, Respeecher, which transmutes one voice into another, said it’d be easier to work with an actor who had a similar register and
