Continuity mistake: When Richard goes for a swim while Em is inside the hut, you can see him under the water with his hair drenched. He then climbs onto the shore and his hair is completely dry and curly again.
Continuity mistake: After the baby is born, in one scene where it is lying on the bed, it's lying on a blue-green print receiving blanket. In the next shot, the baby is wrapped in a fur or rough cloth material.
Continuity mistake: There is a scene in which it is raining quite heavily and Em and Richard are inside the hutch. Richard is playing Pop Goes The Weasel over and over which annoys Em. She stabs him in the foot and he chases her outside. In this scene she is wearing a strapless dress but when he catches her and pins her down on the sand she is wearing a lacey jacket (she didn't have time to change) and there are no clouds or rain. The sand doesn't seem to be very wet either, despite the fact that it was raining heavily a few minutes ago.
Continuity mistake: This mistake takes place when Paddy has grabbed some bananas and is walking through the jungle and stumbles upon God. In one shot as he's hoping over a log, his knife in his belt is on his right side. Soon after when he finds God, his knife in his belt is on his left side.
Continuity mistake: In the scene where Em is ill and Richard takes her to "God" and places her on the rock, she is shown lying on her right side, her face turned to the side with her hair partly covering her face. In the close-up shot of her, she is lying face up and her hair is away from her face. Then in the next shot, she's again on her side with her hair back over her face.
Continuity mistake: When Richard spots Paddy laying on the ground, they sail over to him. As they run up the beach there's hardly any seaweed around Paddy's body. Yet when it cuts there is much more seaweed around him. Also to the right of the screen on the beach, there are some rocks, but when it cuts (in the same shots as the aforementioned mistake) another large rock appears.
