Other mistake: Geena Davis has her hands and feet tied to the water wheel when she's being tortured for information. Under water she manages to free one of her hands but not her feet, when she comes up for air and shoots her captor, she drops the gun and unties her other hand, but her feet are still tied, so she would have fallen face first into the water.
The Long Kiss Goodnight (1996)
1 other mistake - chronological order
Directed by: Renny Harlin
Starring: Samuel L. Jackson, Geena Davis, Craig Bierko, Yvonne Zima
Visible crew/equipment: When Geena Davis is being dunked in water, you can see an air hose she is breathing out of in one shot. It is when the bad guy is talking, and you see her submerged.
Samantha: You thinking what I'm thinking?
Hennessey: I hope not, coz I'm thinking about how much my balls hurt.
Trivia: Scriptwriter Shane Black is a huge believer in recycling. Check out how much the moment when Jackson is captured by Bierko resembles Rigg's capture by McAllister in "Lethal Weapon". Black's 3 biggest movies - "Lethal Weapon", "The Last Boy Scout" and "The Long Kiss Goodnight" all involve a major character's daughter being kidnapped (to say nothing of all beginning with an "L").
Answer: A 1966 Ford Galaxie-500 XL. There's a website that lists the vehicles used in the movie.
