Gunnery Sergeant Hartman: Where in the hell are you from anyway, private?
Private: Sir, Texas, sir!
Gunnery Sergeant Hartman: Holy dog shit, Texas! Only steers and queers come from Texas, private Cowboy! And you don't much look like a steer to me so that kinda narrows it down!
In the opening scene, Gunnery Sgt. Hartman is making his speech and passes by Privates Cowboy and Joker on his way to the other side of the barracks. On his way he passes Private Pyle standing to the right of Private Joker. Later in the scene, when he rushes over to confront Private Joker and then moves on to Private Cowboy and then Private Pyle, Private Pyle is on the left of Private Joker.
Ermey was convinced that the scenes in boot camp wouldn't be believable unless the actors were actually frightened of him. According to the commentary on the blu-ray, when he was acting as the technical adviser and training them to drill, or whatever he was training them to do, he never raised his voice. As soon as the camera was rolling, he started screaming at the actors. Much to Ermey's pleasure, the fear you see on the screen is real. Many times in the shooting the actors would become so flustered by Ermey that they would blow their lines. Ermey recalls that he's seen the other actors in the film around Hollywood from time to time, and they still won't speak to him.
