Chopra is presently in Los Angeles casting for the Bollywood gangster film, which begins shooting in early 2011, the Hindustan Times reports.
A source revealed: "Cage has been confirmed for one of the leading roles just a few days ago."
Broken Horses is a remake of Chopra's earlier hit, the Anil Kapoor and Madhuri Dixit starrer Parinda.
"Broken Horses keeps the soul of Parinda intact. But it explores the same genre in a diverse setup," added the source.
Chopra was recently honoured in a retrospective of his work at the First Indian Film Festival of London.
