Alex Gibney's sprawling documentary "Musk" arrives as an exhaustive reckoning with one of contemporary capitalism's most polarizing figures. The film, which premiered at the Venice Film Festival, stretches nearly four hours and positions itself as a comprehensive biographical investigation rather than a sensation-seeking exposé.

Gibney, the Oscar-winning documentarian behind "Enron: Smartest Guys in the Room" and "The Inventor: Out for Blood in Silicon Valley," constructs his portrait through meticulous research and archival material. The resulting work functions as a forensic accounting of how Elon Musk rose to prominence, assembled his empire across Tesla, SpaceX, and X (formerly Twitter), and accumulated the wealth and influence that now makes him one of the world's most consequential figures. What emerges is less a bombshell revelation than a systematic examination of the structural conditions that enabled his ascent.

The four-hour runtime reflects Gibney's commitment to comprehensiveness over sensationalism. Rather than cherry-picking scandals or focusing on viral moments, he traces the arc from Musk's South African childhood through his early internet ventures, his involvement with PayPal, and his subsequent takeovers of electric vehicles and space exploration. This methodical approach occasionally sacrifices narrative momentum for evidentiary weight, creating a document that reads more like a definitive historical record than a dramatic thriller.

One tension Gibney navigates concerns access. Musk did not participate in the documentary, limiting the filmmaker's ability to secure the subject's own voice explaining his motivations, decisions, and worldview. This absence becomes both constraint and statement. Without Musk's perspective, Gibney relies on interviews with former employees, investors, journalists, and critics. Their testimonies paint a portrait of a figure driven by technological vision but indifferent to the human costs of his ambition.

The "distressing" quality critics note stems not from any single revelation but from Gibney's patient accumulation of evidence about Musk's impact. The documentary examines his influence over public discourse, particularly following his acquisition of Twitter. It investigates workplace culture at his companies, the demands he places on employees, and the ways his personal obsessions shape corporate direction. What emerges is a study of how unchecked wealth and influence concentrate in one individual's hands.

Gibney's film arrives at a moment when Musk's political influence has become impossible to ignore. His acquisition of Twitter and subsequent transformation of the platform into a vehicle for his own political views marks a shift from tech entrepreneur to media kingmaker. "Musk" documents this trajectory without needing to invent drama; the material speaks for itself.

The documentary's significance lies in its timing and its filmmaker. Gibney brings credibility earned through previous investigations of corporate malfeasance and institutional failure. His willingness to spend nearly four hours on Musk suggests the story demands that length, that understanding this figure requires context, history, and patient examination rather than quick judgments.

For audiences seeking a straightforward exposé, the film may disappoint. For those interested in how contemporary capitalism produces its titans and enables their influence, "Musk" offers a thorough, unsettling record of our moment.
