[3] In January 1920, leaving his factory to his assistant, he left for London where he returned to the studios with Mary Massart, who became his muse.

In 1922, he returned to Paris and turned to Gaumont (in the series Pax) My little boy with Leontine Massart, sister of Mary.

This eventful film (one sees in particular a shipwreck) receives a very favorable public and critical reception, due to the originality of the subject and the dramatic use of a new mode of communication, the Wireless telegraphy.

He then returned to the United States with Mary Massart to marry in Los Angeles (they will have a son, Francis Léo) and met the director and producer Edwin Carewe.

In 1943, he made an appearance as an actor in the film Mission to Moscow, where he played Robert Coulondre, French ambassador to Berlin at the beginning of the war under the pseudonym Alex Caze.
