The characters of J.J. McQuade (Chuck Norris) and Rawley Wilkes (David Carradine) were described on movie posters in big bold print as being "The Lone Wolf Lawman" and "The Mad Dog Criminal" respectively.
There were no stunt doubles used for the final fight between McQuade and Wilkes. Chuck Norris and David Carradine insisted to do the scene themselves despite the protests of the producers.
When McQuade pulls Snow from the burning truck, and begins to carry him away in a "fireman's carry," he is twisted up on his side with his arm pulled behind him. When the camera changes angles, he is being carried correctly.
After Snow got pulled out of his burning vehicle and thrown due to the following explosion of the tank-truck we can clearly see his glasses on the lying on the ground, which remains there as McQuade throws him into his car and drives off.
The very next scene, after they stopped on another location, he gets dragged, meant for his interrogation, but this time he is wearing his glasses.
The Burnside character was introduced as an ATF agent, but later in the movie when our heroes invaded the remote airstrip, Burnside proclaimed he was the FBI.
Smith & Wesson Model 629 with a 6" barrel-a nickel plated version of the .44 Magnum used by Clint Eastwood as "Dirty Harry"The 629 is stainless version of the Mod 29 .44 Magnum, it debuted in 1979.
A nickel plated version would be a Mod 29 nickle, nothing more.
Just to clear things up(I hope)
