Audio problem: In the scene where Leo explains how he launders the drug money and Roger says "You're a cheat", Leo says "Come on, everyone cheats a little, look at the pentagon." But when he says "look at the pentagon", it's dubbed in because the sound of his voice doesn't match his other dialogue, and if you read his lips it doesn't match either.
Lethal Weapon 2 (1989)
Directed by: Richard Donner
Starring: Mel Gibson, Danny Glover, Joe Pesci, Patsy Kensit
Continuity mistake: At the end of the movie, when Riggs is in the cargo area, a gunman shoots at him, he rolls and starts emptying the clip into him - you see the bullet holes in the gunman. But as Riggs is face to face with the gunman, the holes disappear.
Deliberate mistake: The way diplomatic immunity is depicted in the movie is extremely inaccurate. While technically a sufficiently ranking diplomat could perform the acts shown in the movie without being subject to arrest, their home government would be requested to turn the diplomats over for trial, or the diplomat would be declared persona non grata and expelled from the country. A drug smuggling ring and murdering multiple policemen is far, far more serious than actual crimes that diplomats have been expelled (or handed over for trial) for in the real world. Additionally, the consul general and his officers would not be considered diplomats. They would only have limited consular immunity with regards to "official acts" in the course of consular business.
Trivia: The first time we see Riggs in his trailer, there's an advert for some new aftershave called "Hero" on the TV. During the attack on his trailer later, there's a close-up shot of a bottle of aftershave being destroyed - freeze-frame it and you'll see the brand: "Hero" again.
Trivia: When Leo is cleaning Riggs' house, you can hear the song "I'm Not Scared" by the group Eighth Wonder. Patsy Kensit, who portrays Rika Van Den Haas in the movie, was the lead singer of the group.
Trivia: Right before Rianne's commercial begins, a Tales from the Crypt episode is on the TV. This is the second episode of the first season, titled And All Through the House about a woman who kills her husband and is terrorized by an escaped mental patient dressed up as Santa. The murderous woman is played by Mary Ellen Trainor, who plays the psychiatrist Stephanie Woods in the Lethal Weapon movies.
Rudd: Now we DO have a serious diplomatic situation here, which I will be taking up with your state department first thing in the morning.
Riggs: Whoa, you got me quakin' in my boots, but I'm still gonna bring you down.
Rudd: My dear officer, you could not even give me a parking ticket!
Martin Riggs: Police! Open up!
Leo Getz: How do I know it's the police?
Martin Riggs: After I shoot you through the door, you can examine the bullet. Open up!
Arjen Rudd: Certain policemen in this city have become an intolerable nuisance. They are obviously onto us again. How do you propose to handle the situation?
Pieter Vorstedt: Warn them off. It's my experience that a scared cop is more useful than a dead one.
Arjen Rudd: A warning... Is that not a bit tame?
Pieter Vorstedt: Depends how you do it.
Question: I have heard a rumour that there is a deleted scene where Riggs kills the two guys who dropped him off the pier in a straight-jacket. Apparently it was too violent to keep in. If this is true then where could I see the deleted scene?
Question: Mel Gibson says "They killed them both." I know he's referring to his wife, but who's the second person?
Chosen answer: Rika Van Den Haas, the South African woman he was seeing whose body he finds tied up under water.
Question: What exactly is Leo talking about with the processing of laundering money? Neither Riggs or Murtaugh get it and I don't either.
Answer: Leo is describing a money laundering scheme, with the intent of taking dirty drug money and making it legit. Money laundering is largely about confusing the source of the money, to make it look like it came from a legitimate source. Leo is saying that the dealer gives the money to a courier, who gives it to a guy to put it into a dummy company. The dummy company writes a check to the courier in the dealer's name. This puts about 5-6 steps in the chain of custody of the money already. The dealer takes out a loan using the check as collateral (let's say a $10000 loan with a $10000 check as collateral). The dealer never repays the loan, so the bank keeps the check (nobody loses because the amounts are equal). This puts even more steps in the chain of custody. If a law enforcement agency wanted to try and track the money back to the source, they would have to unwind all those steps, being able to prove each step occurred with evidence. Very hard to do.
Answer: This scene is already in the movie (maybe only the Director's Cut). Riggs surfaces just off the pier, picks up a chain, strangles one man with it and breaks the other man's neck. The scene is cut considerably for play on television and in all versions of the movie in the UK prior to the 2010 UK blu-ray release (including the Directors Cut) - although some TV airings since 2000 have used the full uncut version.
