Hearsay With Cathy Lewis

Tonight, the TV series "Smallville" will end its 10-year run. The series chronicled how the boy Clark Kent became the ultimate "Man of Steel," Superman. This summer's film lineup is packed with superhero flicks from, "Thor" to "The Green Lantern" and there's a new Superman film in the works for next year. The popularity of Superman and other comic heroes begs the question, why do superheroes exist in the first place? On Friday's HearSay, we'll talk about the evolution of superheroes and how they reflect and emulate everyday people in our lives.
