After Tom disappears in the ocean and Laura finds him by the tree, he is completely dry and is somehow still wearing the suit jacket that he threw off before.
Laura is wearing an off the shoulder dress, but when she returns to her room she is wearing a regular two strap slip.
(at about 39 mins) While Tripler is sitting on the couch, the drug paraphernalia on the table in front of her changes positions from edit to edit.
When Weesie comes in the house naked after streaking, in shadows the strap from her thong is clearly visible.
At the end, when Laura and Tom are standing in pouring rain, their clothes remain completely dry.
