Came across whit this one too. The length is incredible short so you won’t get a very deep plot, right?! It is indeed quite forgettable, but in the other hand it is a nice action packed western-spaghetti worth watching if you have some patience.
Harrison is quite all right as the “King” and Kinski does a very little appearance (I kind of expect that), even shorter is the role of Vassili Karis as the smiling rapist deputy.
I watch the italian dub which has a lot of bad language, as my father uses to say “é só putas e cabrões”. The slang in Italian is very similar to Portuguese so I could’t avoid to expel some laughs during the sofa session.
