It is called The Set-Up. She made it in 1978, around the time she was studying film at Columbia University. It is twenty minutes long. In it, two guys, one of whom is Gary Busey, fight each other. On the soundtrack, two semioticians, Sylvère Lotringer and Marshall Blonsky, deconstruct the images we are seeing. According to last summer's Times profile, Bigelow "now plays down the film," but we don't care. We want to see it so bad.
Or she could remake it! Surely there are semioticians still willing to contribute. As the two people having a fistfight, we recommend Elinor Burkett and Roger Ross Williams.
