Corrected entry: In the scene where Duke and his photographer are riding in the desert, right before those guys come up with the dead deer on the jeep, look at the photographer's mouth. He is talking but you don't hear him.

Correction: The entire scene is shot from a third-person point-of-view but taking into account Hunter's current state of mind (blown out on drugs). Therefore he could have simply never heard the guy talking.
