Continuity mistake: When Riggs and Murtaugh are trying to find the address Leo can't quite remember, Riggs is looking through an address book. Turning the pages, he gets to a yellow bit (possibly a different section), and so goes back a page. The angle changes half-way through this page turn, and the yellow page has disappeared, replaced with a page full of text. (00:34:55)
Continuity mistake: At the end of the film when Murtaugh is holding Riggs, the position of the money keeps changing around them, yet no wind appears to be blowing.
Continuity mistake: In the final shoot-out Riggs shoots a guy who is looking down a ladder. We see about four exit wounds on his back, but no injury in front, neither later when Murtaugh takes a look at the corpse. (01:37:30)
Continuity mistake: In the drive-thru scene you can see that the right half of the grill and both right headlights on the wagon are gone. When they pull up at Roger's in the scene where Leo gets kidnapped the right headlight is working. (00:45:20 - 01:03:15)
Continuity mistake: When Riggs wins his straightjacket bet he pulls it over his head, but only because the formerly closed strap through his crotch is suddenly open. (00:08:40)
Continuity mistake: In the opening car chase the red BMW zips through a hotel arcade. On the right we see a guest waiting with a porter. The porter grabs a suitcase and runs towards the entrance, and the guest turns left and starts running away from the entrance. When the camera angle changes the guest is back where he was standing, but now he turns right and runs the other way. (00:03:00)
Continuity mistake: In the final scene where Riggs is in Murtaugh's arms the side shots show blood all over the left side of Riggs' face but the straight shots there is just a little on his left cheek and chin. (01:41:55)
Continuity mistake: This only for the Directors Cut edition of Lethal Weapon 2. In the added scene where Riggs charms the ladies at he Pool in the hotel where Leo is staying. Just as they wallk in to the pool area, you see a woman in a pink bikini get out of the pool almost completely. Then in the close up shot as Roger bends down to talk to someone, the woman in the pink bikini is getting out of the pool again. (00:26:30)
Continuity mistake: At the end of the opening car chase the red BMW crashes into a police car whose driver vanishes between shots. (00:06:00)
Continuity mistake: When Rika sits down outside of Riggs' place, the front of the trailer is half shaded by the sunroof. When the camera angle changes the shade is gone, and it's much brighter. (01:07:50)
Suggested correction: This entry is only half right - the "sunroof" or awning is visible from both camera angles, though it's true that the sun is lower and is lighting more under the awning when the camera moves inside the trailer.
Continuity mistake: When Riggs is thrown off the tow truck and rolls across the ground the Ryder truck that was just overtaken by the tow truck disappears and reappears between shots. (00:37:25)
Continuity mistake: After Murtaugh confirms the Alba Varden is a ship, one of Rudd's henchmen enters the house armed with a knife. Moments later when they're struggling by the hobby room's blueprint table, Murtaugh grabs the nail gun and shoots him in the forehead. Now right here, you can notice the sound of a knife being thrown to the floor as he reaches for his head. But when the henchman is up against the unhinged doors, he's once again holding a knife in his right hand. (01:21:55)
Continuity mistake: When Riggs loses his gun during his tow-truck ride there's a white fence on the left side of the road. When Murtaugh stops the car and Leo "gets" it, there's no fence anywhere. (00:35:55)
Continuity mistake: After leaving the Embassy, when Murtaugh pulls over after Leo says there's a deli, he parks in front of a white car and is near a bush and some grass on the ground. From inside the car, the white car is no longer present and when the door is ripped off, they are now parked in a different spot, no bush or grass is around.
Continuity mistake: When Pieter throws a knife at Riggs from offscreen, it sticks into his leg. Note that most of the blade is still visible. All things considered, the knife could have been able to penetrate maybe two, three inches into the skin (at best). But look closely in the following shot as well as subsequent shots where Pieter starts kicking Riggs in the face and you'll notice how the knife has managed to drive itself completely through and out the opposite side. Arguably the knife could be long enough and, with immense effort, this might be possible, but Pieter throwing a knife all the way through Riggs' thigh just seems absurd. (01:46:45)
Continuity mistake: When Riggs jumps from Murtaugh's station wagon to catch up with the BMW on foot, he springs onto its rear window and asks the driver for proof of insurance. Interior brake lights are shining on his clothes before he falls to the pavement. Seconds later the driver stops to take a shot at Riggs, but now the BMW is missing the interior brake light altogether. (00:03:40)
Continuity mistake: After Riggs' Houdini-esque underwater escape, he makes his way to the pair of hitmen on the docks above. One of them gets thrown through a car door's glass window, and Riggs uses that same door to bash his head repeatedly. As Riggs is dealing the blows, pay attention during the close-up shots and you'll see reflections in a brand new piece of glass. (01:32:50)
Continuity mistake: After inviting Rika to his trailer, Riggs walks inside and opens his fridge to get a beer. On top of the TV nearby is a VCR. Flash forward to the helicopter attack scene where Rika and Riggs are about to escape through Sam's doggy door. Here you can see there's no longer any VCR on the TV set. (01:14:20 - 01:24:15)
Continuity mistake: When the hotel waiter shoots at Riggs through the flatbed tow truck's rear window, Riggs manages to cling to a handle on the passenger's side and avoid being hit. However, immediately before the waiter runs out of bullets and throws down his gun, look sharp and you'll see how all of the window's busted glass is once again intact, like new. (00:40:50)
Continuity mistake: At the end when the shootout on the Alba Varden has finished, as police cars are shown driving over the bridge while Murtaugh attends to the wounded Riggs in the cargo area, the sky is pitch dark. Two minutes later when the credits are rolling, the sky is now much lighter. (01:46:40 - 01:49:00)
