Revealing mistake: When Shaft and his buds are sneaking into a building to save Bumpy's daughter, a pedestrian momentarily comes into the shot and then quickly steps out when he sees the camera crew. (01:18:45)
Suggested correction: I believe the entry refers to the initial rescue attempt, at 1:18:45. I am not entirely convinced that this is a legitimate goof though: the man sees 3 guys peeking into an alley, and he seems to rather stop and backtrack to check out whatever they are looking up, the exact opposite of 'stepping out'. It's still a rather amusing detail, though.
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. (00:02:50)
