Corrected entry: When the little black kid tells D-Fens how to shoot the bazooka and asks where he is aiming it, D-Fens tells him "That big yellow monster down there" (i.e. a construction truck about a block down) and at this, the bazooka is pointed at the ground, and accidentally goes off. The shell "travels" through some pipe system and then blows up a block away. This is total fantasy. Had this been real, the shell would have exploded right there, killing everybody within about 20 feet. (01:16:00)
Corrected entry: During the golf course scene watch the guy clutching his chest having a heart attack. He clutches the right side instead of the left.
Correction: It should also be pointed out that the clutching of the left side in a dramatic fashion is a Hollywood thing. Your heart is located in the center of your chest with just a small part of the heart on the left side, so often the pain will be in the center of the chest and radiate out.
Correction: There's no mistake here. He's having a heart attack. He's panicked and clutching his chest. There's no rule that you have to clutch the exact right spot on your chest while having a heart attack.
Corrected entry: In the scene where D-Fens fires into the canal construction site he is surrounded by a lot of kids. All but the one he is talking to disappear between shots. (01:13:15)
Correction: It's just the camera angle. They are there the whole time.
Corrected entry: When D-Fens attacks the 2 gang members with the baseball bat he strikes the second guy somewhere between the left shoulder and side of the chest, but later in the car it's the gangster's elbow that is hurt. (00:20:15 - 00:23:30)
Correction: He also fell down a flight of concrete stairs after getting hit. He could have easily hurt his elbow (and other parts of his body not hit with the bat) while falling down the stairs.
Corrected entry: In the fast food scene, it is 11:34, and they stopped serving breakfast at 11:30. However, everyone in the restaurant is eating lunch, hamburgers to be specific, despite only being able to order them for approximately 4 minutes.
Correction: Many fast food restaurants start serving burgers long before breakfast is over, some even serve burgers the whole time.
Corrected entry: Robert Duvall plays a retiring cop. In one scene a uniformed officer comes by and collects his gun. At the end of the movie he draws his gun and ends up shooting Michael Douglas. How did he get his gun back?
Correction: A couple of minutes before Duvall shoots Douglas, Duvall and Rachel Ticotin arrive at the home of Douglas's ex-wife. Douglas shoots Ticotin (not shown in the movie), then flees. Duvall runs to the back of the house to check on Ticotin, who gives him her gun. That would explain how Duvall had a gun when he and Douglas have their showdown moments later.
Correction: Rockets that are not on a timer are set off by a pressure sensor at the nose of the rocket, and it was common practice to "Bounce" rockets off the ground at shallow angles in order to penetrate the bottom of a tank, where the armor is weakest. With the angle D-FENs fires the rocket at it is entirely possible for the rocket to bounce upwards and travel along the channel.
