Two grown men, one house, zero maturity. The guys throw Kevin into Step Brothers (2008), where drum sets are sacred, bunk beds are “so much more room for activities,” and the Catalina Wine Mixer is the biggest deal in town. Will Kevin embrace the chaos of Will Ferrell and John C. Reilly’s man-child antics, or just side with the weary dad trying to hold it all together? Starring Ferrell, Reilly, Mary Steenburgen, Richard Jenkins, and Adam Scott, this comedy is so quotable it just became your best friend.
