Change Of Mind (1969)

A married couple struggles to adjust when the white husband's brain is transplanted into the skull of a black man. David Rowe (Raymond St. Jacques) is the white district attorney who must now live life as a black man. His wife Margaret (Susan Oliver) tries to deal with the transformation of her husband's appearance as David feels the stings of racial prejudice for the first time. Sheriff Webb (Leslie Nielsen) is the local lawman who resents the district attorney, but after the sheriff kills his own black mistress, he must rely on David for his legal defense.
