Every once in a while, something comes along that makes you realize the truth in too much of a good thing can be bad. Allow me to introduce “A Night at the Roxbury,” the new release from Paramount Pictures. The original idea is from the “Saturday Night Live” skit about the Roxbury Guys, named Steve and Doug Butabi (Will Ferrell and Chris Kattan), who spend their evenings in every nightclub in Los Angeles. Even though they get shot down by every woman they approach, it doesn’t faze them, for they continually think they are two desirable, happening guys.The movie keeps this basic idea but elaborates on it, including their father (Dan Hedaya), who expects them to follow in his retail-business footsteps and neighbor Emily (Molly Shannon), who relentlessly pursues Steve.Steve and Doug want no part of their father’s silk plant business, instead setting their sights on creating their own nightclub. First, though, they want to gain admission to the Roxbury, the best of the best in nighttime entertainment.With the help of Richard Grieco, they eventually get in and have the best night of their lives.The problem is, the first part of the movie is so lame, you almost don’t want to stick around to see their success. Banking on elementary gimmicks like knocking girls over on the dance floor and gratuitous high fives, the beginning has less to do with funny and more to do with annoying. What works for ten minutes on “SNL” doesn’t work when stretched out for half an hour.As they actually get into the hallowed Roxbury, the laughs pick up a little, eventually evolving into real humor by the end.The movie does have merits, most notably an awesome dance soundtrack. Doug and Steve perform their spastic best to tunes like the standard “What is Love?,” “It’s a Beautiful Life,” and “Where Do You Go?” There are also some pretty good put-downs and comebacks, plus killer spoofs of popular movies like “Jerry Maguire” and “Say Anything.”Surprisingly enough, the movie also has a hidden message. The Butabis, as pathetic as they seem to us, are so wrapped up in their dreams at first that they don’t let anyone’s comments bother them. However, as they start to listen to everyone’s criticisms, their self-confidence dwindles and they even turn on each other. This allows others to take away their happiness and their dreams.Even with these perks to balance the letdown of the movie’s beginning, it’s not enough. “A Night at the Roxbury” should be saved for a night on the couch after it comes out on video.
