Deliberate mistake: At the end of the film, two officers attempt to surround and handcuff Joshua. Using two officers to cuff someone is NEVER done for the exact reason of what ends up happening, as Joshua manages to grab a gun from one of the officers. Only one officer would have been doing the deed in the real world, but it's clear this error in being completely against police protocol had to happen so the good guys could prevail over the villain.

Continuity mistake: In the scene where the girl jumps to her death from the balcony, it shows her hitting the car towards the right halfway onto the windshield. Then in the next shot, it shows her lying right in the middle of the roof of the car. (00:04:05)
Martin Riggs: Now we both know why I was transferred. Everybody thinks I'm suicidal, in which case, I'm fucked and nobody wants to work with me; or they think I'm faking to draw a psycho pension, in which case I'm fucked and nobody wants to work with me. Basically, I'm fucked.
Trivia: During the scene in which we see Murtaugh talking to Hunsaker about his involvement with the Drug dealers. Hunsaker mentions 'Air America', a CIA front during Vietnam. Air America was a film regarding this very thing, starring Mel Gibson and filmed three years after Lethal Weapon.
Question: In the nightclub, Mel Gibson shoots a guy who says "Hey, what are you..." Was he a bad guy, or was he just a random citizen?
Chosen answer: He was one of Hunsacker's men.
