The first issue of Christos Gage’s adaptation picks up shortly after the third film. Blondie is hunted by both the Union army (for blowing up their bridge) and the Confederates (for stealing their gold).
There are some fairly straightforward action scenes, and not much else besides this set up. Hopefully, as the series unfolds, they’ll be able to develop the more Leone-esque aspects of storytelling.
The Man With No Name #1 is currently available.
