Directed by: Richard Donner
Starring: Mel Gibson, Danny Glover, Gary Busey, Mitch Ryan, Tom Atkins
Audio problem: In the beginning, when Murtaugh's daughter comes downstairs in the black dress the dialog is dubbed in. After the spin, she's talking but she doesn't move her mouth (even before the spin she isn't in sync). Her little sister replies and doesn't move her mouth either.
Audio problem: Right after Riggs handcuffs the suicidal man, the next shot shows Murtaugh saying "oh no" but his lips don't move.
Continuity mistake: When Mel Gibson is talking about the special bullet, kept as the suicide special, he describes it as a hollow point - to do the job right. When he shows the bullet it is a full metal jacket.
Roger Murtaugh: See how easy that was? Boom, still alive. Now we question him. You know why we question him? Because I got him in the leg. I didn't shoot him full of holes or try to jump off a building with him.
Martin Riggs: Hey, that's no fair. The building guy lived.
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: Who's the actor that played the jumper...? IMDB doesn't say... I thought I heard once that it's Mel Gibson's brother? He looks like the character "Johnny" in Mad Max.
Answer: Also, "Johnny The Boy" from the first Mad Max film was played by Tim Burns, according to Wikipedia; not only is he a completely different actor, but he is also obviously not Mel Gibson's brother.
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).
