Matthew McConaughey is set to star in the upcoming true crime movie White Boy Rick, playing the father of Richard Wershe Jr. (Richie Merritt), who was the FBI’s youngest-ever informant turned cocaine dealer in the 1980s. While the full trailer for the film dropped yesterday, it was missing two notable cast members: rappers Danny Brown and YG. A new clip shared by Def Jam CEO (and Danny Brown manager) Paul Rosenberg features both rappers in yet-undisclosed roles. Find that and the full trailer below.

Elsewhere in the film are Jennifer Jason Leigh (The Hateful Eight), Brian Tyree Henry (“Atlanta”), and more. Studio 8’s White Boy Rick opens on September 21.
