Think it's too late to find fame and fortune? Think again. CBS News 48 Hours takes a look at a few people who dreamed of making it big in entertainment. They were regular Joes and Josephines, without million-dollar bank accounts to fund their projects. How did they do? Among the extraordinary people you'll meet on this Thursday's show are: Nicholas Sparks, a pharmaceutical salesman who dreamed of becoming a novelist - and did. He's just finished his third book, and his second book, a bestseller like the first, is being turned into a movie starring Paul Newman and Kevin Costner. Vin Diesel , a charismatic young filmmaker/actor who dreams of breaking through at the famed Sundance Film Festival. Darren Aronofsky , another obsessive filmmaker with dreams of cinematic stardom. Interestingly, both Vin and Darren find success, but follow very different paths.
