- The production couldn't gain access to a U.S. military base in Kuwait, so the whole production was moved to Amman, Jordan.
- During filming, three, four or more hand-held super 16mm cameras were used to film scenes in documentary style. Nearly two hundred hours of footage was shot at an eye-popping 100:1 shooting ratio (a higher ratio of expended film than the notorious Francis Ford Coppola epic, Apocalypse Now (1979)).
- The production had a hard time booking key crew members and department heads, since the film was shot on location in the Middle East (specifically in Jordan, the country right next door to Iraq).
- The Jordanian military provided security for the film. Military were stationed outside of production sets and outside of hotels where cast and crew were staying.
- The first week of shooting (during the summer in Jordan) there was a heat wave. It was so hot that the cinematographer, Barry Ackroyd, took sick with heat stroke.
- Actor Jeremy Renner tripped and fell down some stairs while carrying an Iraqi boy on the film's set. Shooting was stopped for several days while Renner's ankle healed.
- A production bus full of Iraqi refugees (hired as extras) overturned on a road heading to production. Nobody was seriously injured. A few people suffered bruises and one person was reported to have a broken nose.
- Several key American crew members were stopped and questioned and/or had their baggage rummaged through by American airport security prior to going and/or coming back from Jordan. Even one of the producers was held for questioning upon returning to Los Angeles.
- Part of the shooting took place during the Muslim month of "Ramadan". Non-Muslim crew members hid out and ate in tents and specialty hotels with windows covered by carpets (out of respect, and per the Jordanian law). Smoking, eating or drinking in public during daylight hours of fasting is banned in many Middle Eastern countries, including Jordan, and is punishable with jail time.
- Colin Farrell, Willem Dafoe and Charlize Theron were originally set to star.
The three songs in the film by Ministry (Fear (Is A Big Business), Palestina, Phyber Pass) are from their tenth album, the politically driven Rio Grande Blood, which criticizes the war in Iraq and former President George Bush. - James Cameron said this about ex-wife Kathryn Bigelow's film: ""I think this could be the Platoon (1986) for the Iraq War."
- Much is made of the fact that Sergeant James came over from the 75th Ranger Regiment, and he wears a Ranger battalion combat scroll on his right shoulder, which means he went to combat with a Ranger battalion. Oddly enough, he does not wear a Ranger Tab on his left shoulder, which signifies graduation from the grueling Ranger School. This could either be by choice, or he was assigned to a Ranger battalion as an "untabbed bitch," meaning he was transferred to a Ranger battalion right before they deployed, and didn't have time to actually attend Ranger School before they deployed.
- It was James Cameron who convince his ex-wife 'Kathyrn Bigelow' to direct this film. She originally had plans on doing another project and wasn't sure about doing this film. Cameron read it and told her to do this film, she went off doing and as a result, this film ending up being one of most successful independent films of 2009 and the most successful in her career.
