That's something many of us dream of but few can achieve -- sort of like fighting crime in an iron suit, driving a motorcycle with built-in artillery, or looking good in spandex. A new generation of audiences now has him to thank for bringing some of the country's most storied heroes to life on screen. Investors are thanking him, too.
