Vanity Fair really hit it on the nose with the casting. The 22-year-old Brazilian beauty [Camilla Belle] received help from Tony (Ben Barnes, also known as Prince Caspian), Anita (Jennifer Lopez), Bernardo (Rodrigo Santoro) and fellow Sharks played by Brandon T. Jackson (Tropic Thunder) and Jay Hernandez (Grindhouse, Ladder 49). The Jets are played out by Chris Evans (Riff) and Cam Gigandet (The O.C., Twilight), Drake Bell (Nickelodeon’s Drake & Josh), and Robert Pattinson (Twilight).Suddenly that crack I made about "a Jets and Sharks rumble breaking out" seems weirdly prescient.
