  The influence of wall slip on the instability of a non-wetting liquid film
placed on a solid substrate is analyzed in the limit of negligible inertia. In
particular, we focus on the stability properties of the film, comparing the
performance of the three lubrication models available in the literature, namely
the weak, intermediate and strong slip models, with the Stokes equations. Since
none of the aforementioned leading-order lubrication models is shown to be able
to predict the growth rate of perturbations for the whole range of slipping
lengths, we develop a parabolic model able to accurately predict the linear
dynamics of the film for arbitrary slip lengths.
