Emma Roberts

Actress Emma Roberts made her film debut working with one of the best actors in history -- and she didn't even know it. At only ten years old, Roberts was cast as the daughter of Johnny Depp's character in 2001's Blow, but she would later recall that she was too young during the experience to realize what a respected figure her co-star was in Hollywood. In 2004, Roberts joined the ranks at the Nickelodeon network, taking a leading role in the series Unfabulous. The regular gig provided both experience and stability for the up-and-comer, but maintaining a presence on the big-screen remained a goal. In 2006, she made a splash with a leading role in Aquamarine, a comedy about a couple of tween girls who discover a mermaid living in their beach club's swimming pool. The young actress charmed audiences and casting directors alike with her performance in the romp, so much so that she was soon cast in the title role of Nancy Drew in a 2007 revival of the teenage-detective franchise. - Cammila Albertson, All Movie Guide
