Step Brothers is one of Will Ferrell and John C. Rielly's gems. It gets funnier each time I watch it and is and endless wealth of one liners to use with other fans.
The real gold here is the special features; they are worth the price alone. There are hours of improv, extended scenes, music videos, some of the funniest commentary I've ever heard.
If you own this movie already but without the special features disc, double dip. It's like getting hours of hilarity with the movie thrown in as a free bonus.
Excellent movie. The picture quality is top notch as well. The movie itself is one that had me thinking about it for days after watching. The acting was tremendous and it has genre elements for all types: action, sci fi, romance, comedy, drama, etc.
Great movie to add to any blu ray collection and Best Buy had the cheapest price available as well.
