Giovanni Ribisi has joined the cast of Warner Independent's The Rum Diary starring Johnny Depp, Amber Heard, Aaron Eckhart and Richard Jenkins.

According to Variety, he'll play a carousing journalist in the Hunter S. Thompson adaptation.

Written and directed by Bruce Robinson, The Rum Diary details the life and events of Paul Kemp, a freelance journalist who finds himself at a critical turning point in his life while writing for a run-down newspaper in the Caribbean. Paul is challenged on many levels as he tries to carve out a more secure niche for himself amidst a group of lost souls all bent on self-destruction. Thompson delivers a potent story that pushes the sometimes brutal truth of human relations into your face in such a way that it would be absurd to not laugh.

The project, which Depp, Christi Dembrowski and Graham King are producing, begins shooting March 30 in Puerto Rico.

The Rum Diary was released October 28th, 2011 and stars Johnny Depp, Aaron Eckhart, Michael Rispoli, Amber Heard, Richard Jenkins, Giovanni Ribisi, Amaury Nolasco, Marshall Bell. The film is directed by Bruce Robinson.
