4. O.J. Simpson I Can't Be The Terminator, People Won't Believe I'm A Killer
This just had to be on the list even though technically Simpson did not turn down the role. O.J. Simpson was passed over for the Terminator role because the execs thought no one would believe him to be a killer. Fast forward to 1994 and the deaths of Nicole Simpson and Ron Goldman. Apparently his performance in real life proved the execs wrong people still believe that he did it even though a jury of his peers thought otherwise. Perhaps if they added a Bronco chase scene and a bloody footprint to the Terminator movie, the public would have brought into the idea of O.J. Simpson as a killer.
