Jennifer Lawrence is being treated like a "slave" for 'The Hunger Games' franchise, her 'American Hustle' director believes.

The 'American Hustle' director David O. Russell believes the 23-year-old actress - who plays Rosalyn Rosenfeld in his movie - is on the verge of burning out and has compared her stressful workload to Golden Globe-winning film '12 Years A Slave'.
