The breakup of a thin liquid film moving in a second fluid utilizing viscous potential analysis and considering disjoining pressure is studied. The occurrence of cavitation due to local pressure drop in the film has been considered. For a large Weber number and density ratio, cavitation might occur and it could be the main reason for breakup.
