Continuity mistake: In the beginning of the film when Natalie Wood first gets in the limo, she is waving goodbye to her mother who is on the pavement. As the limo is driving away and Wood is leaning out the window waving, there is a lamp post behind her that is so close it looks like it might hit her. When the camera moves back to her mother you cannot see the lamp post.
Continuity mistake: While changing clothes in her mother's trailer, Daisy accidentally buttons her shirt wrong, it's fixed as she exits the trailer to go out to the limo. (00:21:30)
Other mistake: After her mother dies, Daisy puts her head in the oven and turns the gas on by turning the red button clockwise - we can hear the gas. But then someone is at the door, she turns the red button clockwise again, not anticlockwise, and the gas shuts off.
