Langmann began his career as an actor in his father's films when he was a teenager, earning Cesar Award nominations for Most Promising Newcomer for Les années sandwiches in 1988 and Paris s'éveille in 1991, as well as a nomination for Best Supporting Actor in 1993 for Le nombril du monde. He became a film producer in the early 2000s. During the filming of Asterix at the Olympic Games, he was arrested for employing prostitutes and purchasing narcotics. In 2011, Langmann produced the black and white, silent film The Artist with director Michel Hazanavicius. He was unable to attract investors to the risky project and self-financed the film.
