Knightley will star in the clone thriller "Never Let Me Go," according to Variety. The story follows three boarding-school students who discover they're clones bred for organ donation. We're interested to see how this will differ from "The Island," which followed clones who -- you guessed it -- are unaware they're being bred for organ donation.
Clones are big business right now. In February, Eva Green signed on for the lead role in "Womb," wherein Green clones her dead husband.
Knightley, 23, starred in 2008's "The Duchess." She also had a cameo in "Star Wars Episode 1: The Phantom Menace," which series went on to prominently feature clones.
