Pretty Woman

They must have been feeding Julia Roberts tons of different snacks all day while shooting this scene! In one frame, she's chewing on a croissant. The camera switches once and then goes back to Roberts who is now eating a pancake. It's such a small detail that is easily overlooked! This went past tons of eyes before it was released, so this little pastry switch was definitely tricky to spot.

She’s All That

In She's All That, main character Taylor got a butterfly tattoo on her shoulder in an act of careless rebellion. Not too later in the film, she's seen at prom with a backless dress. Somehow, that permanent tattoo faded away. For real, though, how hard is it to put a fake tattoo on for this scene? Or at least pick a dress with a back on it.
