An old western movie. in color. I can´t remenber much of it, but i do remenber a scene where, the two main characters (a man, and a blonde woman) are trapped or kidnapped and being transported into a wagon. The girl ask the man to bite her ropes, the ropes she has on her wrist, and while doing it, her skirt rise up, so the guy used his teeth to bite the skirt or the dress down, before continue to bite the ropes.
There is a scene like that in: Soldier Blue (1970) – http://www.imdb.com/title/tt0066390/
