Dallesandro is generally considered to be the most famous male sex symbol of American underground films of the 20th century, as well as a sex symbol of gay subculture.
Dallesandro starred in Flesh as a teenage street hustler. Rolling Stone magazine in 1970 declared his second starring vehicle, Trash, the "Best Film of the Year", making him a star of the youth culture, sexual revolution and subcultural New York art collective of the 1970s. Dallesandro also starred in 1972's Heat, another Warhol film that was conceived as a parody of Sunset Boulevard. Notes from Wikipedia.
