Indiana Jones and the Dial of Destiny opens with a 25-minute sequence that features a de-aged Harrison Ford fighting Nazis. Director James Mangold revealed this and spoke more about the de-aging process in a recent interview with Total Film.
The movie opens in 1944, with Ford fighting his way out of a Nazi-occupied castle. Mangold said in the interview that he simply filmed Ford normally, with the artificial intelligence-powered de-aging software doing the work to make Ford look younger. Ford had to wear those little dots on his face to record his performance, but other than that, it was business as usual.
“I just shot him, and he just pretended that he was 35,” Mangold said of Ford, going on to describe the actor as “incredibly gifted and agile.”
