Trivia: Hattie McDaniel's portrayal of Mammy earned her an Academy Award, the first to be given to an African American.

Trivia: Actor Richard Davalos kept his bayonet razor sharp and accidentally stabbed Telly Savalas in the arm during the scene where the squad jumps over the wall to ambush the Germans on the road, warranting bandages on Savalas' arm. In the film, Savalas kept his shirt sleeves rolled up, until he was stabbed, and then kept his sleeves rolled down to hide the bandages.

Trivia: Not really a mistake, given the need for drama (and explosions) in a war film, but since we know the mission takes place the evening before D-Day, meaning the Allies had complete air supremacy, and they knew the exact time, date and place of the meeting of the German officers, this mission would never have taken place. The chateau would have been flattened by a squadron of heavy bombers, most likely RAF Lancasters carrying 10,000lb "Grand Slam" bombs. Lee Marvin, an experienced combat veteran, pointed this out to the producers and was told to keep his opinions to himself.

Trivia: When the Japanese are heading towards Pearl Harbor, there is a shot of a pilot waving to kids playing baseball. This is a true story - the pilot was trying to wave them away before the attack started. (01:26:35)

Trivia: Virtually all of the extras who play soldiers in the film were members of Civil War Re-enactor groups who not only freely donated their time but also supplied their own uniforms and equipment. This ensued that the film-makers did not have pay for their own extras and that they could stage the massive battle scenes without blowing the budget.

Trivia: The pivotal role of "Minnesota Ryan", the Private Ryan that Captain Miller mistakes for the Private Ryan for whom he is searching, is played by a very young and, at the time quasi-unknown, Nathan Fillion.

Trivia: The man shooting the movie during the attack on the beach who says "Don't look at the camera" is actually director Francis Ford Coppola. (00:25:38)

Trivia: Due to the political situation in Iraq, the location for scale shots was moved from Morocco to Mexico, an ideal alternate choice with its broad beach. However, the rushed decision presented some obstacles. Coastal Mexico is an endangered turtle habitat, so to be granted permission to set up the Greek encampment and build boats on the large stretch of beach, the film crew implemented their own turtle incubation nursery, releasing a multitude of turtles while on location in Mexico. They also did not have an accurate idea of the physical conditions of that particular beach - it was unstable and 100 feet of beach washed away overnight, leaving Greek ships teetering precariously on the edge of the bank with the missing sand.

Trivia: Nicole Kidman played all her own piano for this movie.

Trivia: Bill Millin, Lord Lovat's piper, earned the nickname 'Mad Piper' due to the fact that he was spared by German snipers on D-Day because they thought him to be crazy playing bagpipes in the middle of a war.

Trivia: Adrian Brody insisted on learning to play the piano himself because he detested the idea of him being in a long shot pretending to play the instrument and then the camera showing someone else's hands on a close up shot actually playing. He said he hated that, not just for him, but on any other film that had such a scene. So he went and took lessons, practicing for hours on end.

Trivia: Conrad Veidt, who played Maj. Strasser, was well known in the theatrical community in Germany for his hatred of the Nazis, and in fact was forced to hurriedly escape the country when he found out that the SS had sent a death squad after him because of his anti-Nazi activities.

Trivia: R. Lee Ermey actually wrote all of Gunny Hartman's dialog himself. Ermey was involved in a serious car accident right before shooting, so Kubrick invited Ermey to come stay at his house in England to recover. While recovering Ermey read the script over and over, and he remarked that the Drill Instructor's dialog that was in the script was obviously the work of a screenwriter with a cliche imagination who obviously had no idea what boot camp was really like. So Kubrick allowed Ermey to re-write all of the dialog himself.

Trivia: While Steve McQueen performed most of his own stunts, the only stunt he didn't perform was the 60 foot jump over the Austrian-Swiss border fence. The jump was performed by stuntman Bud Ekins, who later doubled for McQueen in "Bullitt."
Suggested correction: This not really a mistake is a mistake. The 10,000lb Grand Slam bombs were in such short supply that they were reserved for the most critical targets, certainly not a château.
stiiggyA château full of high ranking, critically important German officers would be right on the top of anyone's target list. Just look at the extraordinary efforts the US Air Force went to to shoot down Admiral Yamamoto's flight.
Yamamoto's plane was shot down by regular squadron of Lightnings, not a specialist squadron like 617. There were many such meetings during the entire war and none were targeted by air. And as I said, the supply of Grand Slams were so critical that infrastructure targets got priority.
