A general mechanism of nonlinear saturation of instabilities in flowing films is described using the Rayleigh-Taylor instability as an example. The combined action of flow shear and surface tension is the essence of the saturation mechanism. As a result, the streamwise perturbations of the interface that would rupture a stagnant film do not rupture a film flowing in a certain range of shear rates.
