For the filmed action Boxing, Grigorescu used the technique of superimposition, layering images to create a double self-portrait. He appears naked, fighting himself. The looping action of this grainy, black-and-white, 8mm film reflects the artist’s frustration with the strict confines of everyday life in communist Romania. Boxing against oneself is a losing battle; his persistence despite the futility of his actions serves as an expression of private resistance.
