Revealing mistake: At the beginning, when the woman in the flotation seat is paddling backwards, you can see a fishing line attached to the back of seat that is being pulled to help her move backwards.
Other mistake: It makes no sense that the pimp would die from having the tip of his tongue bitten off. (00:23:35)
Continuity mistake: During the opening credits, Peter Boyle is seen loading luggage into a red Ford convertible with a rear license plate reading 677 EIY. When he parks in front of the Community Legal Services office, the car's front license plate reads 185 ENV. A few moments later, when he goes to meet Robert Redford, the front plate reads 772 DYD.
