This is absolutely classic! When John Travolta and Samuel L. Jackson are giving Mia Wallace the adrenaline shot, they mark her chest with a magic red pen marker. And after the shot has been given, that red mark has disappeared.
During a shot for one of the scenes in Pirates of the Caribbean: The Curse of the Black Pearl, people noticed something a little odd. You can clearly see that in the background of this picture, there is a cast member definitely not in costume as he’s wearing a white tee and sunglasses. Definitely not a pirate!
