Continuity mistake: At the end, Sarah leaps onto a horse, jumps the fence and rejoins the waiting Apaches.

Continuity mistake: During Victoria's conversation with Vaquero in the tent, the red blanket wrapped around her changes positions (up near her ears, then falling off her shoulders, etc.) several times between takes.
Continuity mistake: When Manolito wakes her up, Anita instantly changes positions on the bed between takes. She's lying on her side, but in the very next shot, she is suddenly on her back looking up at him. (00:20:00)
