Using the membrane stress tensor, we study the fluctuations of the membrane-mediated Casimir-like force. This method enables us to recover the Casimir force between two inclusions and to calculate its variance. We show that the Casimir force fluctuates very strongly. We also study the distance dependence of the variance of the Casimir force. This distance dependence has the same physical origin as the Casimir force itself.
