There is a girl that sneaks into her ex husbands house whille he's at work and turns off the power and steals his gun and when he gets home they start to fight and she pushes him over a rallining and he falls onto a glass table and dies. She wears all black and has rings on every finger and gloves over her hands to hide the rings so when she punches him she will hurt him worse then she thinks. What is the name of this movie. I think angelina jolie plays in it but I'm not positive.

Sounds like Mr and Mrs Smith

I'm pretty sure it's Enough (2002) - IMDb (http://www.imdb.com/title/tt0278435/?ref_=sr_1) with Jennifer Lopez
