Gun Use and One's Love Life

Take it from two experts in romance:

For Angelina Jolie and Brad Pitt, happiness is a warm gun. In an interview with Vanity Fair, Jolie says the two actors came to trust each other while taking gun training for the upcoming "Mr. and Mrs. Smith." In the movie, they play married assassins.

"You had to trust each other to cross under or over and only move when the other person moves, so the trust, when somebody's got a loaded gun at your back ... it made us trust each other quickly," Jolie said in the magazine, on newsstands May 10.
