Krush Groove is a 1985 American musical comedy-drama film distributed by Warner Bros. Pictures that was written by Ralph Farquhar and directed by Michael Schultz (who also produced the movie, along with George Jackson and Doug McHenry). This film is loosely based on the early days of Def Jam Recordings and up-and-coming record producer Russell Simmons (renamed Russell Walker in the film), portrayed by Blair Underwood in his feature film debut. Simmons was the film's co-producer and story consultant; he also had a cameo in the film as a club owner named Crocket.
