A BBC team revisits the boy king's mummy using CT scans and forensic reconstruction to settle a question that has divided Egyptologists for decades: how did Tutankhamun actually die? Virtual autopsy specialists build a digital model from thousands of scan slices, checking his bones for the fracture patterns a chariot crash would leave and testing whether his club foot and other physical ailments left him too frail to ride at all. Historian and scientific interviews walk through the physical evidence found in the tomb, from his walking sticks to traces of malaria in his tissue, weighing disease against injury as the real cause of death. The film also examines his family tree through DNA analysis, addressing the inbreeding within his lineage and what it may have done to his health. Rather than settling on a single dramatic verdict, the documentary lays out competing medical theories side by side, letting the viewer see how much of pharaonic history still depends on reading damaged bone and fragmentary genetic data.
