Debra Miller writes in the book Billy Name Stills From the Warhol Films:

"Superboy was never screened for the public. It remains one of Warhol's unknown films, hitherto uncatalogued in filmographies and unpublished in art historical literature. Nevertheless, one of the images associated with its production - of the young Superstar International Velvet - is among the most famous of Billy Name's Factory Fotos. Above all, the film and its stills comprise an homage to beauty, both male and female. The cast includes an unidentified boy surfer in the title role, along with two of the women featured in The Chelsea Girls, Mary Woronov and International Velvet." (BN70)
