Here are two very different trailers for the exciting spaghetti western film Compañeros (1970, Sergio Corbucci).

Then the American trailer, which features scenes:
Having seen the movie, I like the first trailer better—it's almost a satisfying short film in its own right—but I wonder if only the second could get anyone to actually see the movie, since the first one is kind of vague. In any case, check out the movie, 'cause it's really good (if you like spaghetti westerns, or have only seen the Sergio Leone Clint Eastwood ones). It's on good quality DVD, available from Netflix, etc.
