So we all heard about the spate of Iron Man and Avengers-related films that Marvel is putting into development in the wake of Iron Man's success. But it seems like Shellhead's big box office has done more than that. As a long-time Iron Man fan, and a pretty big comic book reader, I had no idea that Iron Man was considered second-tier. But apparently, he was a huge gamble compared to known superheroes like Spider-Man, Hulk, Batman, Superman and, uh, Ghost Rider. (Okay, I guess they're all pretty big players, but Blade was totally second-tier, and didn't he do pretty well, considering he got two sequels? But I digress.) Anyway, because a no-name superhero like Iron Man did well, B-list heroes are getting booked for big-screen endeavors in a big way.
