How do studios bring deceased actors back to the screen?

Digital resurrection is usually a collaboration between a living performance double and a large visual-effects team—not a one-click AI replacement.

1. A stand-in performs the scene and provides body motion, timing, and interaction.
2. Artists study scans, photographs, and archival footage of the original performer.
3. A digital face is tracked, lit, animated, and composited over the performance.
4. The production clears the needed likeness rights and reviews the ethical implications.
