Re: Howard says that not getting to Reprise his Ironman role killed his career!
I wouldn't say that I've following Howard's career but I do remember him from a sitcom on UPN called Sparks which incidentally co-starred James Avery who was the voice of War Machine in one season of the 90's Iron Man cartoon.
Just some useless fact for yah!
A few of the Marvel Superheroes are somewhat niche characters that aren't extremely versatile, thus they don't have a lot of longevity potential. For example, Namor is a water guy, Silver Surfer is a space guy, Dr. Strange is a magic guy, and so on.
