 In 1934, while working with the Comédie-Française, Perret tried an experimental type of play-documentary from Molière's body of work.Although the experiment was met with limited success, it proved to be an inspiration for other artists such as Sacha Guitry who later created similar types of experimental films.While working on a new bilingual (French-English) talking version of "Koenigsmark", Léonce Perret fell ill and had to be hospitalized at the Saint Jean de Dieu clinic in Paris.
