The Chebychev spectral method provides an estimate of a critical angle of inclination for the onset of instability in a liquid film flowing down an inclined plane. The film becomes unstable with respect to shear waves below the critical angle, depending on the surface tension. The flow becomes unstable with respect to surface waves above the critical angle. The upper bounds of the angle and the lower bounds of the critical Reynolds number for all finite surface tension are presented.
