Jared Leto has enjoyed tremendous success in his life, not only in his career as an actor, but also as a musician and rock star. Not very many artists can boast about having an Oscar and fronting one of the 21st century's most popular rock bands, as Spin has argued. And Leto has managed to keep both careers going strong concomitantly. He and his bandmates released Thirty Seconds to Mars' first album, "30 Seconds to Mars," in 2002, just two years after Leto knocked the wind out of all of us with his performance in Darren Aronofsky's "Requiem for a Dream." The band's successful second album, 2005's "A Beautiful Lie," came out around the time he was sharing the screen with Nicolas Cage in "Lord of War" and with John Travolta, James Gandolfini, and Salma Hayek in "Lonely Hearts."
