Anachronisms: A 2004 Nissan Pathfinder Armada is seen driving by, the movie is set in 2001.
Anachronisms: In the scene with the local police going to Donna McLoughlin's house, a blue police car and a fire vehicle pull up. The blue police car has wheels on it only available on the 2003 and newer Crown Victoria, this movie was set in 2001.
Crew or equipment visible: When Allison Jimeno leaves the house to take a walk, you can see the shadow of a crew member on the sidewalk.
Anachronisms: Multiple characters are observed drinking Bud Light bottles with clear plastic labels. These labels were not seen on Bud Light bottles until 2004.
Revealing mistakes: In a couple shots of Will Jimeno (who is pinned under heavy concrete slabs) the concrete slabs visibly rise and fall with his shallow breathing.
Continuity: As Will is talking about his family, we see a shot of him talking with two rocks on his shoulder. However, after a few other cuts, in the next shot the rocks are gone. Then they are back on in the following shot.
Anachronisms: In scenes outside the Port Authority Bus Terminal, concrete planters are clearly visible surrounding the building. The planters were added to the bus terminal after the September 11th attacks.
Anachronisms: In the early scenes at the Port Authority, there is a wrap-around ad on a building for the Charles Schwab "Talk to Chuck" campaign, which wasn't introduced until 2005.
Anachronisms: During a scene in the hospital near the end of the film, a can of Sierra Mist can be seen on a table. Although this drink existed in 2001, it used a different logo in the 2000-2002 time frame. This logo is from the 2003-2006 time frame.
Factual errors: In one of the opening scenes we see a #2 train, however this train is not a real #2 train. The real #2 trains run on the IRT line, these trains are characterized by being narrower, the train we see in the scene was probably a BMT line train; the BMT line trains look more like the one in the scene and also have a chassis as wide as the one in the shot.
Continuity: At the dinner table, Donna's left hand is visible on her chin from the camera shot behind her, but her hand is not even near her face, on the camera shot in front of her.
Factual errors: At the beginning of the movie, one of the characters asks the Yankee fan if he saw Jeter's home run during Saturday's game. Derek Jeter didn't play the Saturday before Sept. 11 because he was injured. In that game on Saturday, September 8 2001, the Yankees beat the Boston Red Sox 9 to 2. Enrique Wilson filled in at shortstop for the injured Derek Jeter and went 2 for 4 including a triple, with a run and a run batted in.
Continuity: When Allison goes to the CVS with Jerry and Will's sister, her purse strap changes. When the camera is facing her the straps are both over her shoulder, and when the camera is on her back, one of the straps is on her shoulder and the other is hanging down. It switches back and forth between shots.
Factual errors: There is an outdoor scene showing trees with leaves displaying bright fall colors. Leaves in the northeast US don't begin to change until late September and would not be at their peak colors until mid-October.
Factual errors: The scene outside the port authority building has a shadow of AA flight 11 moving over the officer from his right to left, which he followed visually, indicating a northerly flight path at that time of day as the sun would have been in the southeast sky. Flight 11 was headed south and at that time, its path was never between the sun and the port authority terminal, and it struck the north side of the North Tower.
Revealing mistakes: When the rescuers are lifting the concrete slab off of John McLoughlin, the first slab they remove is quite obviously made of painted cardboard and/or styrofoam.
Anachronisms: In the beginning, there is a view of the streets with a crossing sign. However, that type of electronic sign (the one with the hand for "Don't Walk" and the person for "Walk") was not installed until December 2001. At the time of the attacks, the old signs with the words were still in use.
Factual errors: The mall shows Ben and Jerry's Ice Cream being a store when in reality it was a kiosk.
Errors in geography: There is a brief scene set in Hong Kong, where locals are stunned by what they see happening in New York on TV. The background clearly shows that it is daytime. However, when the 9/11 events occurred, it was night time in Hong Kong.
Anachronisms: When Jimeno is dealing with the tourists outside the bus terminal, the shadow of the first plane is cast on the E Walk of The Westin New York at Times Square. This cannot be true, since both the E Walk and The Westin were under construction at the time and opened in October 2002.
Anachronisms: At the beginning of the movie when we see different parts of New York City, you can actually see a modern Dodge Daurango. These SUV's came in 2005 not in 2001.
Anachronisms: During an establishing shot at the beginning of the film, a Honda Element can easily be seen driving past an intersection. This car was introduced in 2003, so there couldn't have been one present in New York in 2001.
Continuity: On the way to the Police Station where Donna thinks she can pick up her husband, the nail polish on her finger nails has disappeared. In the next scene, it is back again.
