First off, let me say this. Iron Man Noir is a fun comic. I enjoyed reading it. What it isn’t, though, is in any way Noir. Like most of the Marvel Noir line, the creators seemed to have no idea what makes Noir, so they just wrote alternate versions of characters, setting stories in the 1930s or so. I think Luke Cage and maybe The Punisher were the only two that got it right.
So, while not a Noir story at all, what we do have is a fun Rocketeer type tale about a Nazi punching Tony Stark on a world spanning quest to find some way of making his mechanical heart keep going. There are ancient artifacts, journeys to lost worlds, and lots of weird twists on classic Marvel characters.
I like these sort of alternate worlds of Marvel, because it lets writers explore the core ideas of the character without dealing with all the baggage of years and years of continuity. And most of it feels right, because like DC Comics, Marvel lifted most of its ideas from the old Pulp stories that this comic emulates.
This one is a lot of fun, and I like the art. It’s worth checking out. It’s just not Noir.
