Nick Broomfield may have been the first to bring hip-hop conspiracy theories to the big screen via his controversial documentary "Biggie & Tupac," but it looks like he won't be the last.

Sylvester Stallone is slated to write, direct and star in a film about the deaths of Biggie and Tupac and the Los Angeles Police Department corruption scandal that lurks beneath the story.

According to Daily Variety, Stallone's project has the working title "Rampart Scandal," and it centers on a massive internal investigation of the LAPD that some say links off-duty officers to the murders of Christopher Wallace, a.k.a. Notorious B.I.G., and Tupac Shakur.

In the movie -- which Variety reports will be shot from several different perspectives like the Japanese film classic "Rashomon" -- Stallone will play LAPD detective Russell Poole. The real-life Poole was a key figure in exposing the corruption in the LAPD's Rampart division, and his interpretation of events is key in the theories that say Biggie and Tupac were killed as part of a gang-police-rap power triangle (see [article id="1457346"]"Biggie Paid Gang To Kill Tupac, Report Says"[/article]).

In Broomfield's documentary, Poole purports that Death Row honcho Suge Knight is the one responsible for Tupac's death. Stallone, who played another corruption-buster in the film "Cop Land," is reportedly approaching Knight to play himself in the movie.
