Exactly 20 years ago today, Tupac Shakur was fatally shot in a drive-by shooting in Las Vegas. Six months later, his principal rap rival, Notorious B.I.G., was gunned down in Los Angeles. Both murders remain unsolved — but now Johnny Depp intends to fix that.

The actor has been tapped to star in Labyrinth, a thriller that has nothing to do with David Bowie’s Goblin King (probably) and everything to do with the two rappers’ murders. Depp will play Detective Russell Poole, a former Los Angeles police detective who theorized that Death Row Records mogul Suge Knight staged the shooting of Tupac to get out of paying him millions of dollars in royalties. Poole also believed that Knight worked with an LAPD officer to kill Biggie in retaliation for Tupac’s murder. He ultimately left the force and dedicated his life to the case, before passing away from a heart attack in 2015.

Labyrinth is adapted from the thoroughly titled 2003 book LAbyrinth: A Detective Investigates the Murders of Tupac Shakur and Notorious B.I.G., the Implication of Death Row Records' Suge Knight, and the Origins of the Los Angeles Police Scandal, by Randall Sullivan. The film, which starts production next year, is being helmed by Brad Furman, who previously directed The Lincoln Lawyer.

Labyrinth is just the latest Hollywood project to take a look at Tupac and Biggie's lives. A new 'Pac biopic, All Eyez On Me, wrapped production earlier this year, and a comedy series based on Biggie's life is currently in development at TBS.
