“Bucky Larson: Born to Be a Star” is a comedy that follows the adventures of a small town grocery bagger’s meteoric rise to adult-film stardom.

Nick Swardson plays the unlikely protagonist: bowl-cut-sporting, buck-teeth-having, twenty-something virgin Bucky Larson. After witnessing his parents in a vintage adult film, he is convinced that his destiny is to follow in their footsteps and leaves the cornfields of Iowa for the bright lights of Hollywood to pursue his new-found dream.

After arriving in Los Angeles, Bucky lands a gig with washed-up adult film director, Miles Deep, played by Don Johnson.

He shows up to his first porn shoot and, well, blows it. Not only is Bucky’s penis so tiny it was briefly mistaken for a vagina, he also has no sexual stamina to speak of.

Despite lacking the natural talents of traditional porn stars, Bucky finds his own special niche and shoots to the top of the adult film world.

If the premise of Bucky Larson made you laugh, you should definitely watch this movie. If you find humor in porn star names, you’re going to love it. And I strongly recommend this comedy to lovers of silly “O” faces everywhere.

But if you don’t think you can sit through 96 minutes of a potato-faced man in a bowl-cut wig and fake buck-teeth spazzing and seizuring with his pants around his ankles, I implore you, do not watch “Bucky Larson: Born to Be a Star.”

“Bucky Larson” is not a terrible movie because it has too much penis humor, or because the porn star names are not clever.

Its not that Bucky’s mid-coitus facial expression doesn’t cause a chuckle. It’s the fact that these three points are expected to substitute for a good plot, well-developed characters, and interesting dialogue.

The film is the latest comedic endeavor from Adam Sandler’s production company, Happy Madison – the same creative group responsible for such crimes against comedy as “Paul Blart: Mall Cop” and the Dana Carvey career-killer “Master of Disguise.” There seems to be a recurring motif with Happy Madison movies.

The protagonist is always a hapless but lovable doofus leaving a bizarro world of crippling love and support and finding acceptance in the “real” world.

“Bucky Larson” is no different. Written by Sandler, Swardson, and Allen Covert, the film falls back on the same tired formula: boy meets world, world accepts boy, boy gets girl, with some potty humor in between.

The only way to make the premise of this spectacularly unfunny script even remotely believable was to make Bucky so incredibly naive, so ridiculously clueless that he doesn’t even know he needs a penis to be a porn star.

Despite Swardson’s brave attempt at making Bucky’s character cute and charming, the thought of a porn star who is unable to fully grasp the concept of sex is just plain disturbing.

The ever-apathetic Christina Ricci plays the role of Bucky’s love interest. She refuses any attempt at being sweet, likable, or even okay to look at, half-heartedly trudging along through the movie, sapping energy from her scenes like a baggy-eyed ennui-stricken vampire.

The only message that she successfully conveyed through her acting in this film was “I need the money.”

Even Don Johnson as pilled-out, past-his-prime porn director, Miles Deep, is disappointing.

His most convincing moments involve his struggles with prescription drugs and ex-wives, a spider web-thin subplot no doubt thrown in as filler sometime in post-production.

The only on-screen chemistry in this film is between Bucky and supporting cast member Kevin Nealon.

Nealon is hilarious as Bucky’s roommate Gary, a petty rage-a-holic who’s beautifully improvised out-bursts were like a breath of fresh air in this water boarding experience of a movie.

The tagline for Bucky Larson reads, “There are no small actors. Just small parts.” By that same token, Bucky Larson is not a terrible movie, just a movie with terrible parts.
