The drainage and withdrawal processes of thin films of popular non-Newtonian models on vertical flat plate under the influence of gravity are considered.  The flow equations are solved for a broad class of viscoelastic fluids using several newly developed techniques.  Expressions for film thickness, and flow rate are made available in compact dimensionless form.  Solutions are compared to that of the Newtonian fluid film.
