Will Ferrell and John C. Reilly have a knack for eliciting genuine laughter, and when they team up, it’s practically a promise of entertainment. That holds true for _Step Brothers_, their 2008 movie. The film centers on _two grown men who haven't managed to get their lives together and are still living with their parents, only to find themselves sharing space after their folks tie the knot._ _Step Brothers_ amplifies the familiar slacker persona to a ridiculous degree, making for an enjoyable experience. The rapport between Ferrell and Reilly is remarkable; when they’re allowed to improvise, the movie really shines. There are some clever put-downs, a ridiculously manufactured scenario, and everyone involved—not just the main actors—delivers a strong performance. This film has become something of a staple in Ferrell and Reilly's work, and it’s always a reliable choice if you're looking for a good chuckle.
