An all time classic manchild comedy by Farrell and Reilly
Step Brothers was part of a run of classic comedies featuring Will Ferrell with director Adam McKay. Ferrell, McKay and the other co-star John C. Reilly wrote the film, and it had co-production by Judd Apatow. Ferrell and Reilly had already created a great working relationship from Talladega Nights released two years before. Like many other Ferrell movies this one is about older men who mentally have not progressed passed high school.<br /><br />The movie focused upon Brennan Huff (Ferrell) and Dale Doback (Reilly) becoming step brothers when their parents Nancy Huff (Mary Steenburgen) and Robert Doback (Richard Jenkins) get married. At first, they truly hate each other. Then they bond over the fact that they both hate Brennan’s brother Dereck (Adam Scott). Afterward they get to play out their manchild fantasies together. Probably the two best scenes are when Brennan and Dale give a presentation on their entertaining company Prestige Worldwide featuring their song Boats and Hoes and then at the Catalina Wine Mixer Brennan sings the opera tune Por Ti Volare while Dale plays drums. Of course the conclusion when they show up at an elementary school is something to behold. At the end they learn that they can be adults while still keeping their inner child. This is the unrated version so there are some cut scenes that were not in the original and extensions of ones that were. They're not essential but they are funny.<br /><br />Again this was one of Ferrell’s top movies. There was no stop in the gags and jokes.
