Director Taylor Hackford purposely kept Louis Gossett, Jr. living in separate quarters from the rest of the cast to further his character's intimidating presence as a drill instructor.
Lisa Eilbacher said the hardest part about doing her obstacle course scenes was pretending she was out of shape. In fact, reports were that she was in the best physical condition of all the actors.
Debra Winger negotiated her own contract (no agent) before she had seen the revised script, and was not happy when she found out that she would be doing a nude scene. She asked to be covered up for the scene, but was told that since she hadn't thought to ask for a "no nudity" clause in her contract, she would have to do the scene as written.
Louis Gossett, Jr.'s Best Actor in a Supporting Role Academy Award win was the first Oscar in that category won by an African-American, and the first for an African-American in any acting category since Sidney Poitier's Best Actor Oscar for Lilies of the Field (1963).
Casting the role of Gunnery Sergeant Emil Foley was very difficult. First, none of the A-list actors approached for the part (including Jack Nicholson) were interested. Second, Mandy Patinkin gave an audition that the producers loved, but director Taylor Hackford nixed their plan to cast Patinkin because he felt the actor was "too ethnic" to play a drill instructor. Finally, the producers did research in Pensacola, Florida and learned that all of the top drill instructors there were African-Americans. This led to Louis Gossett, Jr. being cast for the role that would win him an Academy Award.
