Continuity mistake: As Jack presents Joan with the necklace when they are seated at dinner during the festival scene, the one he is holding in his hand is a beaded necklace, to attract more light for the further camera shot, only when the close up of the table occurs it is a completely different necklace. (01:06:55)
Audio problem: When Jack digs for the statue in the puddle, and he hits it, it makes a sound like iron against ceramics, but the bunny statue is wrapped in hay and cloth. The wrapping is so thick that the spade would not be able to touch the statue, so it would make no sound at all when he hit it with the spade.
Visible crew/equipment: In every shot where "the kid" is driving the red sports car, you can see that there is nobody in the car with him - Elaine should be in the passenger seat. Even slumped over unconscious, she'd be visible. (00:13:25)
Continuity mistake: When Joan is looking for paper tissue to wipe off the tears she sheds over her own book she finally blows her nose with a note stuck to the mirror, saying "Don't forget - buy tissue". The note was stuck on the left side of the mirror, but when she grabs it in close-up it's stuck in the middle. (00:04:45)
Continuity mistake: Right after the bus crash and shootout at the beginning of the movie, it starts to pour with rain and Jack and Joan are walking along the dirt road. The road gives way and Jack and Joan fall down a slope. They end up in a muddy pool and as Jack comes up for air (between Joan's thighs), you can see his wet hair is plastered forward over his ears in one shot and in the next shot it has been pushed neatly back behind his ears - this sequence is repeated a couple of times. (00:31:35)
Continuity mistake: When Joan takes over cutting the leaves in the jungle, she drops the machete when she comes upon the skeleton. Neither she nor Jack bend over to pick it up, but Jack has it in the plane to kill the snake. (00:04:00)
