The Most Beautiful Boy in the World is a 2021 documentary film about Björn Andrésen and the effects of fame thrust upon him when he appeared in Luchino Visconti's 1971 film, Death in Venice. Andrésen was just 16 when the film came out, and was unprepared for instantly becoming an international celebrity.
The title of the film came from a remark that Visconti made about Andrésen at the premiere of Death in Venice in London.
The film premiered at the 2021 Sundance Film Festival on January 29, 2021. It received a nomination for the World Cinema Documentary Grand Jury Prize at the festival.
