We investigate the dynamics of a post-rupture thin liquid film dewetting on a hydrophobised substrate driven by Van-der-Waals forces. The stability of the three-phase contact line is discussed numerically and asymptotically in the framework of lubrication models by taking account of various degrees of slippage. The results are used to explain some experimentally observed patterns. Finally, we present some recent studies of the impact of slippage on the late stages of the dynamics. Here, we present some novel coarsening behaviour of arrays of interacting droplets.
