Revealing mistake: In the scene where Johnny Depp is searching Cheech Marin by the river, you can see Cheech breathing, even though he is supposedly dead from the gunshot in the scene before.
Suggested correction: There is a feature on the DVD that shows the making of this scene, and that a dummy was used.
Incorrect. What they did was use digital effects to blend the fake eye socket of the dummy onto a shot of the real Cheech Marin because the dummy didn't look real enough in close-up. So, that actually is Cheech Marin, and you can, in fact, see him lightly breathing once or twice. The only part of the dummy you can see in these shots is the area immediately around his right eye, where they blended footage of the dummy in. They specifically said on the DVD that the dummy didn't look real enough to be used on its own. I'm not sure how you could have missed that part on the special feature because they show how they blended the two shots.
