My summary is a joke. Yes, the film is Brazilian and involves two cowboys (one of which is the Grim Reaper)--but it is far from being familiar! Its novelty is the big reason why I really liked this film and it's a must-see for lovers of animation and short films.
There are no live actors in this film--other than the hands of the man placing the drawings on the screen (which you can see). The film is a dialog between a mercenary who has been paid to kill Death--not the sort of thing you see every day!
The plot really isn't THE star of the film--the star is the style. It consists of tons and tons of drawings--well done drawings. But how they create a sense of animation to the drawings--THAT is creative and exciting.
I could try to say more about the film but frankly it's really one you just see for yourself...
