Happy Valentine’s Day! Watch Your Favorite Stars Fall in Love On-Screen

Finding a pair of actors who can simulate romantic chemistry on the big screen is a tough task, but as the above video shows, movie casting directors do such a good job that they also end up serving as accidental match-makers.

Some of the greatest Hollywood romances have blossomed right in front of our eyes, including our greatest modern big-star love story, that of Brad Pitt and Angelina Jolie, who met on the set of Mr. and Mrs. Smith and, despite trying to kill one another on-screen, fell for each other in real life.

They’re not the only on-screen paramours to fall for each other in real life: Ben Affleck and Jennifer Garner made goo-goo eyes while making the blindingly bad Daredevil; Ryan Gosling swooned on-screen for Eva Mendes in A Place Beyond the Pines; and The Dark Crystal's Jen and Kira wed shortly after that film's production, and now have a gaggle of Gelflings (or so we've heard). Check out the above video, and feel the love.
