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. Plot Russell Walker has signed all of the hottest acts to his Krush Groove record label, including Run-D.M.C., Dr. Jeckyll & Mr. Hyde (Alonzo Brown), and Kurtis Blow. Rick Rubin produces their records. When Run-D.M.C. has a hit record and Russell doesn't have the money to press records, he borrows money from a street hustler. At the same time, Russell and his brother Run are both competing for the heart of R&B singer-percussionist Sheila E. Also appearing in the film are LL Cool J, Beastie Boys, New Edition, The Fat Boys and some of their songs, as well as others from Chaka Khan, Debbie Harry, and the Gap Band. Members of the R&B group Full Force also make a cameo in the film as bodyguards. Cast The following appeared as themselves, except where noted: Blair Underwood as Russell Walker Sheila E.
