Continuity mistake: When Robin is changing her clothes, after the scene in the water where "something swam up her shorts", she is actually changing out of the clothes she was wearing when the plane crashed, not the clothes she was wearing in the water.
Continuity mistake: When Frank is seated at the nightclub where Angelica performs, watch the light and flowers on the table. When he is seated the light is sitting in the center of a bunch of flowers. Next shot, the flowers are almost gone and the light has moved a good foot or so.
Continuity mistake: When Robin stumbles upon a wild pig, she is pretty close to wading in to the water in the lagoon. Yet in the next shot, she stumbles down a little hill for quite a way before she gets to the water.
Continuity mistake: When Angelica is doing her sexy dance for the tourists, her anklet changes legs between the close up shots of her feet and the far away shots of her.
Continuity mistake: When Quinn and Robin are flying off the island in the DeHavilland Beaver, after replacing the Wheels with Japanese WWII floats found on the island, you can clearly see the brace wires in between the floats. These wires shouldn't be there, since they used bamboo to attach and brace the floats.
Continuity mistake: When Robin and Quinn are standing on the cliff she is afraid to jump, he kisses her and in the shot facing him he has his hands on her face while he is kissing her, but in the reverse shot his hands are not on her face. He didn't have time to move them between shots.
Continuity mistake: Angelica and Frank get in a helicopter to join the search of Robin and Quinn. In the meantime, a day has passed on the island. We come back to Angelica & Frank who are in the helicopter wearing the same perfectly neat clothes as the prior day.
Continuity mistake: While they are approaching, and then running from, the pirate ship, in one shot the horizon is completely empty. Then, in the next shot, the ship is back. This happens more than once.
Continuity mistake: When Angelica is first approaching the charter plane, she has two bags - a leopard print bag and a white bag. Two shots later where she is sitting down in the co-pilot's seat, she only has the white bag. When she gets off the plane on the resort island, she has only the leopard print bag.
Continuity mistake: When Quinn and Robin first escape the pirates just after they row back to the island, they run up a hill for quite a bit. In a later shot they are running along a path close to the seashore, but immediately following that, they are at the higher elevation again as the pirates catch up to them.
Continuity mistake: When Quinn has just prepared the peacock and Robin is ready to take her first bite, she blows on it and they cut to her eating it. In between those two cuts, the way the leg is facing changes directions.
