Corrected entry: When Greg is surfing and lands unconscious on the shore, Marcia revives him and he gets up to walk back into the water. Marcia says 'Greg, where are you going?' Greg replies 'Something suddenly came up.' But any good surfer knows, that you have a leash attached to your foot, that attaches to the surfboard so you don't loose it. However, with the surfboard laying beside him, Greg gets up off the shore and walks into the Pacific ocean, not taking off any leash.
Corrected entry: Tim Mathewson's character gives his nunchucks to Peter. Later Mike Brady confiscates them. When Mike runs a check at the police station on the previous crime history of Tim Mathewson's character, he uses the nunchucks for fingerprints. This would be useless because he would only be getting the fingerprints from Peter Brady.
Corrected entry: When the Bradys land in Hawaii and get off the airplane, they are greeted with flower leis. Marcia gets about 7 leis from cute Hawaiian boys but then in the next scene with Marcia, she is only wearing one.
Corrected entry: When Carol comes in to see Peter in the den, I could swear she calls him "Tim".
