Indiana Jones et le cadran de la destinée

In an interview with Stephen Colbert, Harrison Ford explained how the filmmakers digitally de-aged him for the flashback sequence: "They have this artificial intelligence program that can go through every foot of film that Lucasfilm owns. Because I did a bunch of movies for them, they have all this footage, including film that wasn't printed. So they can mine it from where the light is coming from, from the expression. I don't know how they do it. But that's my actual face. Then I put little dots on my face and I say the words and they make [it]. It's fantastic." At 80, he is the oldest actor to be de-aged in a movie, surpassing Al Pacino, who was 79 when he was de-aged in The Irishman (2019).

Indy and Helena dive at a shipwreck supposed to be 2,000 years old with its wooden hull clearly visible and recognizable. In most waters, such as the ones of the Aegean Sea, wood does not last more than a couple of decades. In fact, Greek and Roman shipwrecks in the area are found by their non wooden materials, such as bronze, and their cargo, such as vases and ceramics, which is where the actual Antikythera mechanism was found.

The Paramount Pictures logo appears normally, and does not fade into a mountain-shaped opening shot, the only film in the Indiana Jones films to do so.

Instead, the Lucasfilm logo fades into a lock on a door in 1944 Germany.

On the International prints of the film, the original variant of Disney's 100th anniversary logo (with 100 YEARS OF WONDER tagline) was shown as the first logo instead of tagline-less variant of the same logo.
