The setting is 1930's but the relatively youthful Garner and Willis and the glamorous western feel make it feel like it was filmed in the 70's. The plot is a typical Saturday morning western, albeit quite violent in parts. Although the acting is good and the villains (of which there are many)are all detestable, it does drag on. There is a long irrelevant scene of Mexican dancing in the middle during which I nearly lost the will to keep watching.
I was a bit disappointed at first because I thought it would be a comedy (what with it being a Blake Edwards film), however there are funny moments in it, and I'm glad I rented it. This film has: a mediocre first act; a terrible middle act; and an amazing final act.
The acting is good (especially from Garner & McDowell), it's very well made, and the story idea is great (it's about an evil film producer who thinks he can get away with anything, so it's aged brilliantly). The problems are: the side characters aren't introduced to us well; and it's hard to follow the plot (until the superb final act, that is).
In conclusion, this is a good film (when you understand what it's about).
