The stability of thin liquid films is of importance in problems of coating solid surfaces. Mainly, when the goal is to have a smooth free surface after the film solidifies. Sometimes the wall has small deformations which have to be taken into account. The goal of this talk is to present recent results on the non linear stability of the free surface of liquid films flowing down smoothly deformed vertical walls. It is also of interest to show the important influence on the stability of the finite thickness and thermal conductivity of the wall.
