Movie posters for the film featured a long blurb that read: "Dr. Don Jardian. Age: 29. Surgeon. Drafted. Vietnam. Nothing could have prepared him for the danger, the fear, the violence ... or the woman".
The lead female role of Deborah Solomon was played by Cheryl Ladd who had the same last name of the production company producing the film, it being The Ladd Company. The sharing of the same LADD name was apparently purely coincidence.
The film's title, "Purple Hearts", refers to one of the highest military decorations that can be awarded to a soldier of the US military, "Being wounded or killed in any action against an enemy of the United States or as a result of an act of any such enemy or opposing armed forces". About forty years before this film was made, another Hollywood movie utilized the medal as a movie's title, with the release of the World War II picture The Purple Heart (1944).
The second film in Sidney J. Furie's trilogy of Vietnam War pictures. The first was The Boys in Company C (1978), about infantry soldiers in basic training and combat. Purple Hearts (1984) was packaged with the promotional subtitle "A Vietnam Love Story". The third is _Going Back (2001)_, the story of Vietnam veterans returning to the war torn country decades later with a television film crew. Furie's The Veteran (2006), re-used footage from Going Back with newly shot material. Furie only took the job on The Veteran because they were going to re-use his footage anyway, and he wanted control over it. Furie also directed a trilogy of military-themed pictures in the aughts: American Soldiers (2005), The Four Horsemen (2008), and Conduct Unbecoming (2011).
