Rosario Dawson's 2010 action flick, Unstoppable, co-starring Denzel Washington and Chris Pine, hits DVD shelves today. In the film, Dawson plays Connie, an attractive yardmaster responsible for figuring out how to prevent a runaway train from a head-on collision with another oncoming locomotive on the same track. While the film sounds thrilling, its heroic ending is easy to predict. What we can't wrap our heads around, though, figuratively speaking, is how Dawson's super-twos have been been so overlooked. It must be that her quality roles and performances, from Kids to Seven Pounds, keep us rightfully focused on her acting ability. Damn, she got us there. But, ultimately (in both movies and real life), she can't stop the inevitable. Do yourself a favor and behold Dawson's 10 best breast moments.
