Check out this picture of Chris Pine showing off his quite large bulge while wearing some white briefs in the 2010 flick Unstoppable. The scene was quick, so you couldn't really see a full view.
Also check out the bonus pictures i added in the gallery. The pics show Chris in sexy gray boxer briefs in the 2009 movie Star Trek!
5 pictures & video inside!
