Continuity mistake: As Arnie runs after Leigh at the drive-in, he arrives under the awning with his hair slightly wet, but still rather full-looking. But in the next close-up, it's soaked flat onto his head. (00:45:40)
Factual error: When we first see Fatima Blush, she is waterskiing. She is doing several stunts, which are only possible with one ski, the most notable being skiing backwards with one foot in the air. However, when she releases the tow rope and skis up the ramp into James Bond's arms, she is on two skis. (00:45:55)
Continuity mistake: When Jeanie is telling Richie the order, she alternately holds the pad, or it is down on the table. The pencil in her hands disappears in one shot too. (00:07:15)
Visible crew/equipment: At one point Clint Eastwood is out in the woods practising his shooting with his new .44 auto-mag pistol. While he's doing this, a car pulls up and a black male begins to get out with a shotgun. (We later learn that this is his partner). As the man with the shotgun is opening his door, if you look at the reflection in the car window, you can clearly see the reflection of a man with a camera and another man standing next to him.
Continuity mistake: At the end, just before Bronson shoots Warren in the forehead, Warren's hair goes from messy to perfectly neat. (01:39:45)
Continuity mistake: In the motel chainsaw scene, before the Colombians pull out their guns, there are several food containers, a bag of cookies and a soda can lined up neatly on a table, seen in multiple shots. After the skirmish, Hector pulls the chainsaw out of its box and Tony is leaning against the table with the items now all scattered in different positions. A few minutes later, Manny shoots his way in. You can see the table in multiple shots and the items are back in their original positions.
Continuity mistake: When Roy Scheider's partner is killed, he is run over by a car. After the car runs him over, his body rolls and you can see his arms swinging freely even though his hands were bound by the plastic ties. Later when you see his body, his hands are bound again. (01:10:30)
Visible crew/equipment: About one hour and fifty minutes in, the two stars get into a fight and are rolling around the floor. In at least one scene, a cameraman, with a handheld Panavision camera, is quite visible in the middle of the shot.
Continuity mistake: When Rita is telling Frank about what happened after Sandra's wedding, she jumps from standing at the right side of Frank's table to the left side. (00:56:25)
Revealing mistake: There's a short ramp by a truck's cargo bed, but when the bikers ride over it, it's become a longer ramp that goes up to the cabin to allow for the stunt. (00:06:14)
Revealing mistake: When Doris the TV repairwoman exclaims, "You crazy? You fed a baby chili?," it then cuts to a closeup of Megan, and this closeup is a flipped shot; everything is backwards. (00:35:25)
Continuity mistake: When Cho chases the van, he grabs on to one of its ladder steps. In the close-up, he's holding on by the ladder bars.
Visible crew/equipment: When Pony Boy, Dally and Johnny are pulling up to the burning church, just before the first one jumps out of the car if you look through the windshield you can see the water truck that's going to put out the fire after they shoot the scene.
Factual error: As the computer repeatedly tries different bombing strategies, all resulting in "WINNER : NONE", one of the strategies it lists misspells "Israel" as "Isreal" and "Palestinian" as "Palistinian."
