When first released, this movie was 2 hours and 45 minutes long and entitled 'Duck, You Sucker'. Leone originally intended the film to be part 2 of a 'Once Upon a Time' trilogy ('Once Upon a Time in the West'; 'Once Upon a Time, the Revolution'; and 'Once Upon a Time in America'). However, for some reason the idea was dropped and 'Revolution' turned into the rather unimaginatively titled 'Duck You Sucker', which was then cut down and again retitled 'Fistful of Dynamite' for audiences in the USA.
Two scenes are missing from this version. The scene where Juan meets one of the leaders of the revolution is sorely missed as it gives added depth to the story, as well as balancing out the movie somewhat in terms of its main themes.
Even with the missing parts, this is still (in my opinion) one of Sergio Leone's best movies. The interaction between the two main characters is excellent, and Leone is on top form as he shows how each of the main characters are changed by the influences of the other.
Unlike Sergio Leone's other 'Spaghetti Westerns', this one is a bit more cerebral, and tends to focus more on character development and to a certain extent on political philosophy. Some don't like this, but I find that out of all of Leone's movies, this is the one that I always find myself coming back to, which is why I finally purchased it on videotape.
I hope that sometime in the near future, this forgotten classic will be reissued in widescreen DVD format, and restored to its original length. As I said before, the deleted scenes help the story, and widescreen format is essential, given Leone's penchant for super close-ups.
