Natalie Portman's troubled western has hit another roadblock two days after director Lynne Ramsay failed to show for the first day of filming; her co-star Jude Law has reportedly quit the project.

Just hours after Warrior director Gavin O'Connor had been drafted in to replace Ramsay, Deadline.com is reporting that Law is no longer among the Jane Got a Gun cast.

O'Connor is expected to pick up the production on Thursday (21Mar13), and his first task could be to find a new leading man.

Law's alleged departure is the third blow for the film - Michael Fassbender also dropped out due to scheduling conflicts with X-Men: Days of Future Past.
