Corrected entry: In the opening scene when Riggs and Murtaugh are driving through the tunnel, Riggs states over the radio that they are "East bound, on foot..." when they are driving a vehicle. (00:00:40)
Corrected entry: This film was banned in South Africa in 1989. The trailers played on TV but after about a week the movie disappeared without a trace. It was eventually shown on TV in 1998.
Corrected entry: There's no way Riggs could have got to Rudd's building before Rudd did. Given that Rudd had a head start (after running the red light), Riggs somehow managed to not only beat him, but find a parking spot, steal a sign and be there waiting, while Rudd was doing a straight drive there. There's simply no way.
Corrected entry: In the beginning, when Riggs and Murtagh are chasing the BMW the red police beacon can be seen flashing inside the windscreen. When it then cuts to a conversation between Riggs and Murtagh inside the car and you can see the beacon but it's not on. Then it then cuts to the outside of the car and the beacon can be seen flashing once again.
Corrected entry: Murtaugh and Riggs are partners since the first movie, they've been working cases together, drive together, Riggs has extra clothes at Murtaugh's house and yet Riggs had no idea that Murtaugh was having construction done, asking if it was an oxygen tent. Murtaugh is showing Riggs the garage and hobby room as if he'd never discussed it with him before. And it's not as if they just broke ground, the job is halfway complete, with the frame up and all. Obviously the dialogue was done for the viewer, not for the characters.
Corrected entry: In the scene where Murtah is fighting with the two guys in his garage he shoots them with a nail gun. These nail guns run on compressed air, yet there is no air hose attached to the gun. You can see this when he raises the gun to shoot the guy through the plastic.
Corrected entry: When Riggs is being attacked at his trailer, his MP-5 continues to blaze away. The MP-5 will empty a 30 round magazine in about 3 seconds.
Corrected entry: In the scene where the toilet blows up, smashes through the window and hits the station wagon, it is clear that the windshield on the car has been broken already and duct taped in place.
Corrected entry: When Riggs confronts the South Africans in the Embassy, he beats up two of them before aiming his gun at Arjen, Vorstedt, and the two other remaining South Africans. However, after he shoots the fish tank, there are three South Africans scrambling to pick up the fish as Arjen directs them, and Vorstedt was not one of them (he remained standing ahead of the tank). No-one else could have entered the room, and it isn't plausible that either of the two that Riggs viciously beat would've recovered so quickly.
Corrected entry: Right before a chase ensues near the stilt house, at the point where the hotel waiter hijacks a flatbed truck at gunpoint, notice how its passenger side door has no mirror (all it's got is a metal assembly, no mirror). But moments later when Riggs climbs along the truck and tries to get a better look him, he does so through a passenger side mirror. How did it get there in the midst of a chase? (00:39:30 - 00:40:30)
Corrected entry: The building used for the South African Consulate is actually a bank. When Roger and Leo are thrown out, the glass front doors are marked with winged logos and consulate lettering that is dark in color, but one door has additional white lettering that says "Open to Serve You, Monday - Thursday 9am-4pm, Friday 9am - 6pm"- rather out of character for a consulate. (01:06:30)
Corrected entry: When Riggs emerges from the water after he has freed himself from the straightjacket he knocks out the two bad guys using both his arms. This wouldn't have worked as he had to dislocate his shoulder to wiggle himself out of the jacket, and he relocates it only after the fight. (01:24:55)
Corrected entry: When Riggs is on the recovery truck, he drops his gun and it lands on the left side of the road, but when Leo picks it up after Roger stops the car, its now on the opposite side of the road.
Corrected entry: When Murtaugh meets up with Riggs before he destroys the stilt house, you hear the tires of both their vehicles screech as they stop, yet they are on a gravel road.
