Continuity mistake: Director's cut (or extra scenes on Lethal Weapon 4 DVD): When Riggs is sitting there at the beginning of the movie, he is crying and looking at the picture of his wife on the right and wedding day on the left. Earlier in the movie when the picture was setting on the TV set his wife's picture was on the left and his wedding day picture was on the right. Not only that, but in at the start the pictures are in a folding frame. During the near-suicide scene they are not. [The first scene shows Riggs has damaged the frame, and says to the photo of his wife, "I'll buy you a new one." which explains the later changes.]
Continuity mistake: In the scene just after the jumper, Murtaugh pulls Riggs into a room and asks Riggs if he wants to die. He hands Riggs his pistol. When Riggs puts the pistol to his temple you can see and hear him cocking the hammer. After some arguing about the positioning of the gun, Riggs then puts the barrel unter his chin. While he's pulling the trigger the camera goes to a close-up of the pistol and shows the hammer pulling back, as he squeezes the trigger. (00:34:40)
Continuity mistake: A quick shot from the interior of the General's car looking at the approaching bus, a metal guard is seen on the front of the bus, painted white to match. It is not there in the shots before or after. (01:42:15)
Continuity mistake: In the scene where they bring Murtaugh's daughter and her arms are bound, when she puts her arms over her dad's head her watch is on her right wrist. After they hang her arms over the pipe her watch is now on her left wrist. (01:28:05)
Continuity mistake: When Riggs is talking to Mr. Joshua before the electrical shock treatment starts, every time the camera shows a side shot the water is covering his head and face, but every time the camera angle changes to the front he is completely dry and the water is in the background nowhere near him. (01:20:20)
Continuity mistake: When the bus hits the General's car, the bus windshield (at least on the driver's side) is all smashed up as seen from the shot inside the bus. However, when the bus backs up, and in later shots of it, the windshield is undamaged.
Continuity mistake: In the scene where Riggs is jumping off the bridge when chasing Mr. Joshua, first he has a rifle in his hand, his shadow on the bridge shows no rifle, when he lands he picks the rifle up off the ground and keeps running.
Continuity mistake: After Murtaugh teams up with Riggs they walk through a parking garage. A police car drives by them twice (at walking speed, with its lights on - in the garage), first in a closer, then in a wider shot, while the dialogue continues, ruling out any artistic intention of this repetition. (00:20:25)
Continuity mistake: When Riggs is standing in the schoolyard during the sniper scene, he is standing on a large rubber safety mat near the monkey bars. But the close-up of his feet shows he is standing on bare concrete (Director's Cut). (00:13:10)
Continuity mistake: In the last shot before Amanda crashes on the car, the red car in front is parked in a different angle than when she is lying on the roof. (00:03:55)
Continuity mistake: When Riggs and Murtaugh walk toward Dixie's house before it blows up, they're wearing large clear glasses, almost like the safety glasses they were wearing at the firing range. After the house blows up they aren't wearing them anymore or even seen taking them off. (00:56:20)
Continuity mistake: When Murtaugh clips on another target it's crumpled at the side. When it comes back after he has shot, it's clipped on straight. (00:55:00)
Continuity mistake: Towards the end of the meeting between the General and Mendez, Mendez steps backwards and bumps into one of the General's men. He turns around and makes some jerky moves with both arms. The camera cuts to the General, and we see Mendez in the background colliding with the other guy once again in exactly the same way as before. (00:24:25)
Continuity mistake: During the drive-by shooting it's raining heavily. When Riggs and Murtaugh leave the scene by car the streets are dry, but when they arrive at Murtaugh's house they are wet again. (01:08:10)
Continuity mistake: At the shooting range, just after saying "That's very thin", Riggs has his arms outstretched, semi-aiming his gun. Cut to a two-shot, and he's got his arms into his body. (00:52:55)
Continuity mistake: As Murtaugh is interviewing Hunsacker, Riggs waits outside on the grass. At one point, the area Riggs is standing still in changes from full sun to full shadow in seconds. (01:13:15)
Continuity mistake: When Amanda is first shown lying in bed, she is wearing her left shoe, but not the right. When she steps up onto the railing, the shoe is on her right foot, but this looks to be a mirror image, possibly on the sliding glass door - fair enough. But when she's lying on the roof of the car, she's wearing both shoes. (00:02:00)
Continuity mistake: The bad wound on Murtaugh's left shoulder (the one which got salted) disappears when he and Riggs drive back to his house. (01:32:35)
Continuity mistake: When Riggs and Murtaugh are driving to the house in Beverly Hills to shoot the guy in the pool, Riggs is lighting a cigarette and then Murtaugh says "You're not gonna smoke in the car." Riggs answers "Yes, but I'm gonna roll down the window." In the previous shot you can see that the window is already rolled down. (00:38:20)
Continuity mistake: When Riggs and Murtaugh kick Murtaugh's front door open they must have damaged the lock, but when the door falls closed the lock sounds as if it is perfectly OK. (01:09:15)
Answer: The jumper's name was Len McCleary. He was played by Michael Shaner and is credited for the role in the film (and on IMDB).
