Revealing mistake: During the credit sequence with the iconic Isaac Hayes theme, occasionally passersby look into the camera, but given the camera placement and the amount of people involved it's hard to label that as mistake. At one point tho, around the 2:50 mark, some tall dude walks into frame and waves a "black power fist" for the camera - he couldn't be greeting Shaft with the gesture because he does it when Richard Roundtree has already walked well past him.
