We present observations of the strongly non-linear behaviour of a single circular soap film undergoing large-amplitude harmonic oscillations in the acoustic frequency range. In such a film, liquid is re-distributed towards its centre, which leads to striking mode formations and consequently to the ejection of droplets from the film. Both processes, liquid re-distribution and droplet ejection, finally result in the rupture of the film.
