She appeared in several films under her husband's direction, including Le grand jeu (1933), Pension Mimosas (1934), La kermesse héroïque (Carnival in Flanders) (1935) and Les gens du voyage (1937). Rosay spent the duration of World War II in Switzerland, where she taught acting classes at the Conservatoire de Genève, although she still appeared in films during this time.
