What is that razor-blade thing with the mustard-colored base sitting against Jamie Stuart’s (or some other guy’s) cheek in this NY Film Festival video? I don’t get it. I’m looking for help. Really. The slogan — “You’ve never done this before…have you?” — alludes to the nominal uniqueness of the 46th incarnation of the NYFF. (Right?) I waited all day to post this because I couldn’t figure what to say.
