Michael Marshall was a French-American actor born on September 13, 1944, in Cedars-Sinai Medical Center, a hospital located in Hollywood. Following his parents' divorce, his father ensured he received an American education. Initially, Marshall pursued a career in law, but his true passion lay in acting. He later joined his mother in Paris, where he began taking drama classes under the guidance of Raymond Griard.
Marshall's early film career saw him work under the direction of renowned filmmakers, including Robert Thomas, who adapted Marcel Achard's play "Potato" into a film. Prior to directing his first film, Marshall had already appeared in two overseas productions, one directed by his father and the other by Vincente Minnelli. His step-father, Gérard Oury, offered him a role in the film "La Grande Vadrouille" as a young Canadian airman, as well as a doctor in "Le Coup du parapluie".
Marshall went on to have a long and low-key career as a character actor in French cinema. On stage, he starred in productions such as "Croque-monsieur", "Le Vallon", and "Point de feu sans fumée". Additionally, he appeared in several television series.
Marshall was the only child of American actor-director William Marshall and French actress Michèle Morgan, and he was also the stepson of Gérard Oury. Furthermore, he was the half-brother of Tonie Marshall and fathered six children. Marshall passed away on June 2, 2005, at the age of 60, leaving behind his mother.
