After being shot, the first target falls face-first onto his grocery bag. In the next scene, he is lying face up.
When the Israeli hostages get into the helicopter, they are all blindfolded. When they get out of the helicopter, none are blindfolded and one is even wearing glasses.
When Avner and his wife are making love in New York, he is drenched in sweat and his hair is soaking wet. His wife wipes his face and his wet hair is visible. In the next shot, his hair is dry.
At the end of the film, when Avner's wife Daphna touches his face, her nails are polished. After they have sex, her nails are not polished.
When dialing the phone number of the bomb-trapped phone for the second time, Carl begins with a different digit than he did the first time he called.
In the film, the German snipers at the airport were using rifles with telescopic sights. In reality, the Germans were criticized for their lack of preparation, including the fact that none of the snipers had telescopic or infrared sights.
Israeli weightlifter Yossef Romano is portrayed as a fit man who attempts a rescue, which eventually results in his death. At the time of the kidnapping, Romano was injured, and walking with crutches.
The film shows Gen. Zvi Zamir being informed of the death of the hostages by phone in an office with an Israeli flag (presumably his own in Tel Aviv). In reality, he was present at the airfield in Munich during the shootout itself, and would have learned the fate of the hostage there, not by phone.
An assault rifle is fired into a bed, making the bedclothes burn. Unless the rifle is loaded with incendiary ammunition - and the illegality of such ammunition makes this eventuality highly unlikely - the bedclothes should simply be riddled with holes rather than burning.
When Carl goes into the apartment building lobby to "sweep" the scene of the first assassination, he picks up a spent shell casing that is clearly a .22 Caliber shell. The assassins were both armed with Beretta M1951 model pistols, which fire 9mm. (Interestingly, the actual assassins in real life likely used Beretta Model 70s, which do fire .22 Caliber.)
Late in the film Avner makes a telephone call from a booth on a street apparently in Brooklyn. He gives the phone's area code as 212. This was correct at the time the movie was set - Brooklyn changed to the 718 area code in 1984.
While having dinner after they killed the female assassin, the team says they killed six of their targets; they had killed seven.
In fact, the team says they had killed six of their targets AND one replacement. Which is what they had killed: six of the list of eleven and the replacement of one of them (the KGB contact).
At the beginning of the movie, the Munich Olympic kidnappings are on TV. Actors are watching the footage on screen as if it was happening live, but the date of the events is displayed on the ABC news coverage. The news footage is clearly archive footage.
Just before the credits roll, Avner asks probing questions of Ephraim. They are in a small park on the north end of Gantry Plaza State Park, near 48th. Ave. & Center Blvd., just north of Avalon Riverview, Queens West, Long Island City. SSE across the East River are the high-rises of Peter Cooper Village behind Avner and to his left (our right), and the low-rises of Stuyvesant Town directly behind him. The World Trade Center towers have not been digitally added to these shots - "Break bread with me, Ephraim" - but have been added to the pullback about a minute later.
In discussing a large money payment to locate the first target, Wael Zwaiter, Avner jokingly refers to James Madison as the American he is supposedly working for while holding up a Franklin $100 bill.
Though they took the time to digitally add the World Trade Center to the final shot, they didn't edit out the Citigroup Center, Trump World Tower, and the Bloomberg building, which were built after the time of the movie.
The reel-to-reel tape recorder used in the debriefing is a Revox B77, which came on the market in 1978.
When the first Palestinian target (the translator of 1001 Nights) turns at the corner at his house, right before his assassination (around the 37th minute of the movie) a modern parking meter is visible with a sign of a cellular phone.
When Avner and Ephraim are walking along the beach in the middle of the film, a jet-ski appears in the water. Jet-skis were invented in 1976.
When Avner checks his TV, he is holding a MagLite in his mouth. The first MagLite was introduced in 1979, and the model he's holding was introduced in 1984.
When Avner is waiting for the Palestinian's daughter and wife to come out of their building, before letting off the telephone bomb, the little girl says the same line twice. Off-screen, she says hello to her driver before she actually meets him. She comes out, repeats the same line, and says hello to the driver when she meets him.
When leaving Papa's farm, the camera and two operators are reflected on the side of the car.
When Avner and Ephraim are walking along the beach in Tel Aviv, the sea is to the left and the sun is casting shadows towards the camera, revealing that they are walking north. The scene must have been shot on the east coast of Malta, not in Tel Aviv, on Israel's west coast.
When Avner meets Andreas and his friend Tony in a Rome café, there is a huge statue of Queen Victoria, in her extremely distinctive pose, in the middle of the square, with the British coat of arms on the pedestal, betraying the location as Malta.
When Avner is on the airplane to Geneva, the flight number starts with SA, for South African Airways, which has never flown to Geneva.
Golda Meir wishes "mazel tov" to Avner's unborn daughter. (So do team members at their first meal together.) Saying "mazel tov" on an unborn baby is bad luck.
In Greece, just before the large explosion, Avner, who is supposed to be fluent in German, asks "Kann ich ein Licht haben?" as he asks for a light for his cigarette. The person responds "sind Sie Deutscher?" ("Are you German?"). The correct question is, "Kann ich Feuer haben?"
In one scene a chess game is briefly visible in the foreground. It is turned the wrong way, with a black square, rather than a white square, in the lower right corner.
