Lethal Weapon (1987)

Visible crew/equipment: Riggs handcuffs himself to the depressed businessman. They jump off the building but they're not handcuffed to each other anymore. They used plastic cuffs which could separate during the stunt in case anything went wrong. They break just as they jump, so they grab each other's hands to stay in contact.

Continuity: 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 laying right in the middle of the roof of the car.

Continuity: During the scene where the General is escaping in the car and Murtaugh shoots the driver. When the car is hit by the bus on the avenue you can see part of the device that makes the car flip over and roll away from the crash.

Mel Gibson references the Three Stooges several times in the film. In real life, Gibson is a big Stooges fan, and in 2000, he produced the biographical TV movie "The Three Stooges."

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 the Vietnam. Air America was a film regarding this very thing staring Mel Gibson and filmed three years after Lethal Weapon.

The helicopter from which Hunsacker is shot by Mister Joshua is FAA registry number N230CA, meaning it's the same Bell JetRanger wearing a POLICE paint scheme that is shot down in the movie 'Blue Thunder' (1:21:30).
