Björn Andrésen

In addition to being an actor, Andrésen is a professional musician, and until recently performed and toured regularly with the Sven Erics dance band. In 2021 Andrésen was the focus of The Most Beautiful Boy in the World, a documentary detailing his experiences post-fame after the premiere of Death in Venice.

Eager to dispel the rumours regarding his sexuality and to shed his "pretty boy" image, Andrésen avoided homosexual roles and parts which he felt would play off his good looks, and was irritated when feminist writer Germaine Greer used a photograph of him on the cover of her book The Beautiful Boy (2003) without his permission. Greer consulted photographer David Bailey (who owned the copyright for the image) before publishing the book. Andrésen maintained that it is common practice when a party uses an image of a person which has been copyrighted by a different individual to inform the individual and that he would not have given his consent for Greer to use his picture if she had informed him of her plans.

Andrésen has appeared in several other films. These include Smugglarkungen (1985), Kojan (1992), Pelikaanimies (2004), and Midsommar (2019).

Andrésen resides in Stockholm. He has a daughter, Robine (b. 1984), with his wife, the poet Susanna Roman. Andrésen and his wife Susanna had another child, a son named Elvin, who died of sudden infant death syndrome at 9 months of age. Andrésen fell into a long depression following the death of his son. In an interview in 2020, Andrésen stated that he believes he will meet his son again "in the afterlife". Andrésen has two grandchildren, a boy and a girl.

Andrésen had only appeared in one film, En kärlekshistoria (1970), at the time he was cast in Death in Venice, which gained him international recognition. Andrésen's role was as Tadzio, the beautiful young Polish boy with whom the film's older protagonist Gustav von Aschenbach (played by Dirk Bogarde) becomes obsessed. Film historian Lawrence J. Quirk commented in his study The Great Romantic Films (1974) that some shots of Andrésen "could be extracted from the frame and hung on the walls of the Louvre or the Vatican". Following the Cannes Film Festival a year after the premiere of Death in Venice, Andrésen received international headlines as "the most beautiful boy in the world".

Björn Johan Andrésen (born 26 January 1955) is a Swedish actor and musician. He is best known for playing the 14-year-old Tadzio in Luchino Visconti's 1971 film adaptation of the 1912 Thomas Mann novella Death in Venice. He also played a minor role in Ari Aster's 2019 folk horror film Midsommar.
