Chris Rock and Morgan Freeman are outside of Rosa's apartment, looking in the trunk of Betty's car. The cut-out of Dr. David Ravell pops out. Chris Rock throws the cut-out on the ground and stomps on it. Chris Rock has on white tennis shoes. Later, when Chris and Morgan are inside Rosa's apartment, Chris Rock is wearing black tennis shoes when he is with the sheriff, taking his gun and handcuffs.
The 'stain on our country's history' line as Morgan Freeman used in the scalping scene is the same line as Morgan Freeman used in his role in 'lean on me'.
