Keira Knightley is in negotiations to star opposite Adrien Brody in new film The Jacket.

Brody stars as a soldier convicted of murder who, during his treatment in a psychiatric hospital, begins to believe he is travelling through time.

Through his time travel, he searches for Knightley, who plays a woman he met as a child and is fated to love.

Steven Soderbergh, George Clooney and Peter Guber will produce the Warner Bros movie, in which Knightley will adopt an American accent.

Production begins in the UK in January for director John Maybury, after Knightley finishes filming King Arthur.

Guber told the Hollywood Reporter: "Keira is a great young talent and has proven her ability to garner critical acclaim and drive theatre audiences.

"Together with Adrien, we have a tremendous cast to complement an exciting script. We're very confident this will be a winning proposition for all involved."
