Turns Out 'Get Hard' Stars Will Ferrell and Kevin Hart Don't Know Each Other Very Well

'Know Your Co-Star' is an interview game we play here on Yahoo Movies where we test how well acquainted two actors have gotten from the experience of making a film together. We've tested the likes of Cameron Diaz, Jason Segel, Daniel Radcliffe, and Lily Collins, and they’ve all done pretty well in answering questions about their colleagues’ life and career.

We figured our latest contestants, Get Hard stars Will Ferrell and Kevin Hart, would do pretty well. Not only did they spend plenty of time together filming the movie, which follows a filthy rich finance exec (Ferrell) who enlists the help of Hart’s working-class family man to help him prepare for a pending prison sentence. But they also have numerous stops together on the promotional circuit, including a recent appearance at SXSW.

We were wrong. Very, very wrong. Watch the awful truth above, then watch the movie’s trailer below. Get Hard opens Friday.
