art and artifice

Susan Sontag did one of Andy Warhol's 'screen tests', which weren't screen tests in the normal sense, but just the subject being filmed for 3 minutes doing nothing or whatever they wanted. Here's a video about it: SSscreenttest. 

What I find fascinating about this short video is how naturally Warhol and Sontag interacted. I imagined that would be the case. In most interviews I've seen, Warhol comes across as kind of affected, as if he's playing a role or wearing a mask, but here he's very natural and very funny.
