Trivia: Val Kilmer has been quoted as saying that screenwriter Kevin Jarre insisted the actors wear real wool costumes, in accordance with the time period. During the scene in the Birdcage Theater, Val Kilmer says, a thermometer was placed on the set, and it read 134 degrees Fahrenheit. Kilmer suggested jokingly that this was the reason Doc Holliday killed so many people: "It's just, like, he wore wool in the summer, in the Arizona territory, and that made him mad."
Trivia: The portable devo guns Mario & Luigi use to turn Koopa into slime are actually Super Scopes, (used in the Super Nintendo Game "Super Scope"). They're kind of the Super Nintendo version of the Nintendo Zapper from "Duck Hunt" for NES (Nintendo Entertainment System").

Trivia: The movie Sniper is actually a factual story loosely based on the biography of a United States Marine Corp Sgt. Carlos Hathcock. Sgt. Hathcock was a sniper during the Vietnam war. A book called "Marine Sniper" written by Charles Henderson has the same stories where Tom Beringer crawls across the field to get into range to shoot the drug lord and also where Berenger is stalked by the enemy sniper where he shoots him the other sniper and the bullet goes through the rifle scope. Those two scenes actually happened in real life.
