During World War I, Decoin served as a pilot. After that he worked as a sports journalist for L'Auto, L'Intransigeant and Paris-Soir. In 1926 he published his first book, influenced by Dadaism, the experimental and prize-winning Quinze Combats (Fifteen Rounds), in which a boxing match is seen subjectively by a boxer, and in 1933 directed his first film, Les requins du pétrole (The Oil Sharks).[2]
He was known for tackling many genres; with adaptations of Georges Simenon as The Strangers in the House (1942) - featuring Raimu in one of his famous roles, and The Truth Of Our Marriage (1952), historical films like The Case Of Poisons (1955), and The Iron Mask (1962), espionage flicks like The Cat (1958), police procedurals with Raid on the Drug Ring (1955) and Fire To The Powder (1957), psychological dramas in Green Domino (1935) (where he first met his second wife, Danielle Darrieux), and The Lovers Are Alone In The World (1948) and even an odd film noir like Between Eleven And Midnight (1949). He worked with such stars of French cinema as Jean Marais, Louis Jouvet, Juliette Gréco, Lino Ventura, Corinne Calvet, Anouk Aimée, Jeanne Moreau and Jean Gabin; to name a few.
He directed Darrieux in several films, and accompanied her to Hollywood in 1938 while she signed a Universal Pictures contract. He took the opportunity to observe how Hollywood made films, and returned to France with these techniques in hand. Decoin was one of the more prolific directors of his time.

Decoin was married four times. His second marriage was to actress and singer Danielle Darrieux. He had two sons, Jacques Decoin (1928–1998) and Didier Decoin (b. 1945), who is also a prominent screenwriter.[3]
