After playing the wanted fugitive and notorious criminal Whitey Bulger in Black Mass, Johnny Depp is heading to the other side of the law for his new project Labyrinth. The actor has been set to star in this true crime thriller that is being shopped to buyers at the Toronto International Film Festival this week. Producer Miriam Segal will be shopping the project, which intends to start filming later this year.

Screen Daily reports that Johnny Depp will portray Russell Poole, the real-life LAPD detective who investigated the unsolved murders of rappers Tupac Shakur and Notorious B.I.G. in the late 1990s. Although he encountered a number of dead ends, his determined investigation uncovered corruption within the LAPD itself. Russell Poole was featured in the 2002 documentary Tupac and Biggie. He retired from the LAPD in 1999 and started his own private detective agency. Russell Poole passed away last August from an apparent heart attack.

Brad Furman (The Lincoln Lawyer, The Infiltrator) is directing from a script by Christian Contreras, based on the book of the same name by Randall Wallace. Good Films is financing and distributing, with UTA and WME Global jointly representing the U.S. rights as the project is being shopped around. It remains to be seen if casting for other roles is under way or not.

Poole's investigations uncovered that a number of slain LAPD detectives were connected to Death Row Records founder Suge Knight. His investigation unearthed evidence that some LAPD officers may be tied to the murders of both rappers. This past Tuesday marked the 20th anniversary of Tupac Shakur's murder in Las Vegas, with The Notorious B.I.G.'s death in Los Angeles coming six months later. Both the murders of Tupac Shakur and Notorious B.I.G. remain unsolved to this date.

Johnny Depp most recently starred as the Mad Hatter in Disney's sequel Alice Through the Looking Glass and in Kevin Smith's new indie Yoga Hosers. He will next be seen in the long-awaited sequel Pirates of the Caribbean: Dead Men Tell No Tales as Jack Sparrow, and he is also attached to portray The Invisible Man for Universal. Stay tuned for more updates on Labyrinth.
