Continuity mistake: (Spoiler Alert) the day after Hancock finds out that Mary also has powers, he stabs her with a large fork with two pointy ends. As expected, they do not puncture her skin. The pointy ends bend toward each other, making a triangle shape. But in the next shot, when Mary snatches it from his hand, the tips are no longer in a triangle shape, just bent the wrong way a little. Mary snatches it away by the handle, so we know that she could not have taken it by the points and bent it.
