After obtaining his BA at an early age, Alexandre Mehring left the academic world to devote all his energy to the Cinema. He was passionate about images, editing and directing and soon became a self-taught filmmaker. After writing and producing his first short-film, Tricycle, at 23 years old he entered several festivals and quickly attracted the attention of advertisement production companies. Subsequently, he began a career as a director in the publicity world.​

In the following twenty years, Alexandre wrote and produced additional short-films and medium-length film (A deux sur la comète, La vraie nature, Made in Taiwan, Voute Plantaire, La Boucle, Obtus, Très Haut...) that were screened, some winning awards, in festivals around the world.  Simultaneously, Alexandre directed around 160 publicity films for the French and international markets. He occasionally worked on the production of other films by directors in the same milieu.
