Wavy dynamics of thin films shows a number of outstanding features: widely separated solitary-like pulses in the homogeneous films with moderate Reynolds number (coarsening, or inverse cascade), striking kinematic instabilities in multi-layer films, and beautiful droplets in the flow down a cylindrical wires. The investigation of these features shows, among other results, that (i) the conventional long-wavelength and multiscale expansions are in fact not applicable to the films with moderate Reynolds number, and a new approach is proposed instead, or (ii) that surface tension may destabilize the plain shear flows, contrary to orthodox view. I will outline the new results of the field, together with demonstration of real experiments.
