Continuity mistake: At the end, when Dianne's "taxi" shows up, Scott and Dianne go for a drive in Scott's car. The rearview mirror is gone in their close-ups, but it's back in its proper place mounted between the windshields in wide shots. (01:35:35)
Continuity mistake: When Dianne and Scott (as Tom, the water-ski instructor) head out on the second water skiing session, in the long shots of the boat, its windshield's center walk-through is open, but in the close-ups of Scott, the windshield's center walk-through is closed, then it continues to go back and forth. (00:29:30)
Continuity mistake: While Scott and Tom are working on the boat's engine, and then while Dianne is with Scott, there's a boat near them with registration number "F 0258 ML" at its side. When Scott is alone after Dianne leaves, the boat's registration number is now "CF 0258 ML" at its side. (00:52:35 - 00:57:10)
Revealing mistake: After Scott and Tom switch places, during the drive down to the hotel, in some close-ups there's black tape covering the motorcycle's chrome trim. (00:06:35 - 00:07:10)
