John Singleton wanted Sidney Poitier to play professor Maurice Phipps. He was not available. Singleton's second choice for Professor Phipps was Samuel L. Jackson; the studio preferred Laurence Fishburne, who had worked successfully with Singleton in Boys in the Hood (1991).
The film was heavily cut upon its release, eliminating much of the romantic relationship between Jennifer Connelly and Kristy Swanson's characters including the resolution to it, along with more scenes involving the Nazi's and the other groups activities and relationships going throughout the University.
Originally John Singleton wanted 'Leonard DiCaprio' to play Remy, while 'Michael Rappaport' was originally going to play Scott Moss.

The idea for the film came when Director Jonathan Demme approached John Singleton about making a movie about college racial issues throughout the country when they were in pre-production for Boyz N The Hood which was being developed at Orion Pictures with Singleton directing and Demme producing. Once the deal with Orion Pictures fell through, Singleton took the idea and began to develop it while at Columbia Pictures.
The fictitious college of Columbus University where the film takes place was actually around South Central Los Angeles with the production designer Keith Brian Burns turning some old dilapidated houses into frat houses.

Dustin Hoffman was originally considered for the role of a the professor that becomes a mentor to Malik. Hoffman wanted the plot to revolve around the professor and the student, but Singleton refused.
