Mozzhukhin
Around 1918, Lev Kuleshov edited a short film in which shots of actor Ivan Mozzhukhin, looking into the camera, were intercutted with fragments of various objects. The audience praised the acting skills of Mozzhukhin; first an object made him hungry, then sad, etc… In reality the audience always watched the same shot of the actor, in which he actually looks quite expressionless.
Cowboy Bij Nacht is curious about the theatrical implications of this experiment, and invites the audience to act as a test person.
