Throughout her career, Dietrich had numerous affairs, some short-lived, some lasting decades, often overlapping and almost all known to her husband, to whom she was in the habit of passing the intimate letters from her lovers, sometimes with biting comments. When Dietrich arrived in Hollywood and filmed "Morocco" (1930), she had an affair with Gary Cooper, even though he was having another affair with Mexican actress Lupe Vélez. Vélez once said, "If I had the opportunity to do so, I would tear out Marlene Dietrich's eyes." Another one of her affairs was with actor John Gilbert, known for his professional and personal connection to Greta Garbo. Gilbert's untimely death was one of the most painful events of her life. Dietrich also had a brief affair with Douglas Fairbanks Jr., even though he was married to Joan Crawford at the time. During the production of "Destry Rides Again", Dietrich started a love affair with co-star James Stewart, which ended after filming stopped. According to writer/director Peter Bogdanovich, Marlene Dietrich told him during an aircraft flight that she became pregnant as a result of the affair but had a surreptitious abortion without telling Stewart. In 1938, Dietrich met and began a relationship with writer Erich Maria Remarque, and in 1941, the French actor Jean Gabin. The relationship ended in 1948.
