Jean-Claude Van Damme was personally offered a role by Stallone, but turned it down. This reportedly lead to Dolph Lundgren being cast instead. Kurt Russell also turned down a role. The role accepted by Forest Whitaker was originally conceived as a role for Wesley Snipes but later rewritten for Whitaker. Due to a scheduling conflict prior to filming, Forest Whitaker was replaced by Curtis Jackson for the role of Hale Caesar, who was then in turn replaced by former NFL player Terry Crews.
