Venice film festival: Alex Gibney interviews former colleagues, wives, the trillionaire’s father and a CG avatar in this absorbing documentary

‘Elon is a nuke.” The speaker is Ashley St Clair, a former conservative Maga influencer and one of Elon Musk’s former girlfriends-slash-baby mommas.

She is a fascinating expert witness in Alex Gibney’s four-hour epic study of the world’s richest and dullest man: the overgrown brattish South-African-born trillionaire plutocrat, ersatz visionary and Trump courtier who owns Tesla cars, SpaceX rocket ships, Starlink satellites on which nation states’ military capabilities are increasingly reliant, X (formerly Twitter) which shapes the collective incel id of billions and GrokAI whose vast server farms daily guzzle oceans of precious water.
