Los Angeles: Oscar-winner Russell Crowe has joined the star cast of Mark Wahlberg's 'Broken City'.

The political thriller is being directed by Allen Hughes from a screenplay by Brian Tucker, a report stated.

The film's story is about an ex-cop who is hired by the mayor to look into whether his wife is cheating on him. After the detective confirms the mayor's suspicions, the wife's paramour turns up dead and a larger scandal begins to surface.

Crowe will play the duplicitous mayor to Wahlberg's investigator.

Wahlberg, Hughes, Randall Emmett, George Furla and Stephen Levinson are producing.

Crowe last starred in 'The Next Three Days' and 'Robin Hood' and will next be seen in 'Man of Steel'.
