Heroes: Where Are They Now? (PHOTOS)

In 2011, Hayden Panettiere portrayed the title character in Amanda Knox: Murder on Trial in Italy, the Lifetime TV movie about the famous Amanda Knox trial. She also had a role in Scream 4, along with every other starlet in the world.

And, of course, she's on the small screen again as one of the stars of ABC's new show Nashville, in which she plays a hot, young country singer named Juliette Barnes.
