Kunis joins Washington's 'Eli'

Mila Kunis has joined Denzel Washington in the cast of action thriller The Book Of Eli.

The Albert and Allen Hughes film follows a lone man who crosses a post-apocalyptic American wasteland carrying a book that holds the key to saving humanity.

That '70s Show's Kunis will play Solara, a woman sought out to betray Eli (Washington), who eventually becomes his ally.

Gary Oldman is also expected to star as the villainous Carnegie.

Kunis's movie career has taken off this year with appearances in Forgetting Sarah Marshall and Max Payne.
